好记性不如烂笔头,记下遇到过的问题,方便以后查阅.

###1. Error:(11) No resource identifier found for attribute ‘roundIcon’ in package

问题原因: 无法找到定义的roundicon资源. roundicon是新版本中出现的,在老版中是没有roundicon的.

解决方法:删除AndroidManifest.xml里的android:roundIcon=”@mipmap/ic_launcher_round”

###2. Error:(1, 0) Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to “831b8e220b7bb0cbbb244f1328f1d4fd5da9” Fix plugin version and sync project Open File.

问题原因:

解决方法:将

dependencies {   classpath 'com.android.tools.build:gradle:2.0.0-alpha3'}

改成

dependencies {    classpath 'com.android.tools.build:gradle:1.+'}

###3. Error:(24, 13) Failed to resolve: com.android.support:appcompat-v7:23.+ Install Repository and sync project Show in File Show in Project Structure dialog

问题原因:

解决方法:SDK Manager中 下载Google repository 和 Android support repository.

###4. FATAL EXCEPTION: main Process: com.viking.jninetndk1, PID: 6145 java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “__aeabi_memclr4” referenced by “/data/app/com.viking.jninetndk1-1/lib/arm/libjniLib.so “…

问题原因: targetSdkVersion版本和NDK版本不匹配.

解决方法: 修改NDK和targetSdkVersion版本号.
android studio :2.0 preview 4
android sdk :android-sdk_r24.4.1-windows
android ndk :android-ndk-r10e
gradle : gradle-2.10-all

android {compileSdkVersion 23buildToolsVersion "23.0.3"defaultConfig {applicationId "com.viking.myapplication"minSdkVersion 15targetSdkVersion 23versionCode 1versionName "1.0"ndk{moduleName "jniLib"abiFilters "armeabi","armeabi-v7a"}}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'}}}dependencies {compile fileTree(dir: 'libs', include: ['*.jar'])testCompile 'junit:junit:4.12'compile 'com.android.support:appcompat-v7:23.+'}

###5. libcooee.so: has text relocations
问题原因: 编译.so文件时使用了较低版本sdk,而project 中的配置 targetSdkVersion22 大于so编译时使用的sdkversion

解决方法: 只需要把功能中的targetSdkVersion降低.

defaultConfig { applicationId “com.example” minSdkVersion 16 targetSdkVersion 22 versionCode 1 versionName “1.0” }

###6. Gradle version 2.10 is required. Current version is 2.8. If using the gradle wrapper, try editing the distributionUrl in F:\work\qxueyou\gradle\wrapper\gradle-wrapper. properties to gradle-2.10-all.zip

问题原因: gradle版本要2.10 当前是2.8.

解决方法: 将项目中gradle目录中gradle-wrapper.properties文件中的distributionUrl=https://services.gradle.org/distributions/gradle-2.8-all.zip修改成与自己gradle匹配的distributionUrl=https://services.gradle.org/distributions/gradle-2.10-all.zip

###7. A problem occurred evaluating project ‘:app’. Failed to apply plugin [id ‘com.android.application’] Gradle version 2.2 is required. Current version is 2.10. If using the gradle wrapper, try editing the distributionUrl in /Users/brindy/Projects/TestApp/gradle/wrapper/gradle-wrapper.properties to gradle-2.2-all.zip

问题原因:

解决方法:
将项目中gradle目录中gradle-wrapper.properties文件中的distributionUrl=https://services.gradle.org/distributions/gradle-3.0-all.zip修改成与自己gradle匹配的distributionUrl=https://services.gradle.org/distributions/gradle-2.8-all.zip

distributionBase=GRADLE_USER_HOMEdistributionPath=wrapper/distszipStoreBase=GRADLE_USER_HOMEzipStorePath=wrapper/distsdistributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip

###8. Error:(1, 0) Minimum supported Gradle version is 3.3. Current version is 3.2

问题原因: 支持的Gradle最小版本为3.3 当前版本为3.2

解决方法: 将

 dependencies {classpath 'com.android.tools.build:gradle:2.3.1' }

改成

dependencies {classpath 'com.android.tools.build:gradle:2.2.0'}

###9.
问题原因: 网络请求更新gradle失败.

解决方法:settings->Build,Execution,Deployment->Gradle 将use default gradle wrapper 改为use local gradle. 将使用网络的gralde设置成使用本地的gradle.

###10. unable to access android sdk add-on list
问题原因:

解决方法: 需要到Android Studio的bin目录下找到 idea.properties 这个文件。使用记事本或其他编辑器，打开这个文件，更改disable.android.first.run 的值等于true,即disable.android.first.run=true 如果没有则直接添加.

###11. ‘It seems that you device does not support camera (or it is locked)’

问题原因:相机权限的问题,Android6.0 之后需要动态配置权限

解决方法:在手机端 setting -> app -> 权限 -> 添加权限

###12. FATAL EXCEPTION: main Process: com.viking.jnidemo, PID: 27114 java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file “/data/app/com.viking.jnidemo-1/base.apk”, zip file “/data/app/com.viking.jnidemo-1/split_lib_dependencies_apk.apk”, zip file “/data/app/com.viking.jnidemo-1/split_lib_slice_0_apk.apk”, zip file “/data/app/com.viking.jnidemo-1/split_lib_slice_1_apk.apk”],nativeLibraryDirectories=[/data/app/com.viking.jnidemo-1/lib/arm64, /vendor/lib64, /system/lib64]]] couldn’t find “libjniLib.so”

问题原因: 无法找到libjniLib.so 库

解决方法:将jnilibs的资源目录引入,sourcesets中添加 jniLibs.srcDirs=[‘libs’]

sourceSets {main {java.srcDirs = ['src/main/java', 'src/main/aidl']jniLibs.srcDirs=['libs'] jni.srcDirs =[]}}

###13. FAILURE: Build failed with an exception. Execution failed for task ‘:app:mergeDebugResources’. Some file crunching failed, see logs for details
AAPT: libpng error: Not a PNG file
AAPT err(Facade for 197782496) : No Delegate set : lost message:libpng error: Not a PNG file

问题原因:说文件不是PNG文件，可是没有说是哪一张图

解决方法:在build.gradle里加入

android {......aaptOptions { cruncherEnabled = false }}

###14. Error:Execution failed for task ‘:app:compileDebugAidl’.

问题原因: 这个是我AIDL文件从服务端复制到客户端,包名没有修改.
解决方法: 仔细看看自己的AIDL文件,是否有写错什么?

###15. FATAL EXCEPTION: main

问题原因: binder调用了错误的接口.

解决方法: 服务端与客户端都要有相同的接口（使用到的），这里的“相同”是指完全相同，包括包名，也就是说要在不同工程下AIDL文件建立相同的包名.

###16. FATAL EXCEPTION: main Process: com.viking.testjar,
PID: 21432 java.lang.UnsatisfiedLinkError:
No implementation found for int com.viking.myapplication.JniMethod.NetInit() (tried
Java_com_viking_myapplication_JniMethod_NetInit and Java_com_viking_myapplication_JniMethod_NetInit__)
问题原因:无法找到so库里面的方法.是没有加载so库导致的.

解决方法:添加加载so库即可.

static {System.loadLibrary("jniLib");}

###17. FATAL EXCEPTION:main Process:com.xxx.xxx, PID: ….
java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “_aeabi_memclr4” referenced by “/data/app/com.viking.xxx-2/lib/arm/libxxx.so”…

问题原因: 这可能是你sdk和ndk版本不匹配导致的.

解决方法: 将sdk和ndk改成匹配的就可以了,至于什么版本与什么版本匹配,可以上网找找.

###18. Fatal signal 11 (SIGSEGV), code 1, fault addr xxx in tid xxx (g.xxxxx)

问题原因:
1.jni开发中出现空指针问题.
2.jni开发中出现索引越界问题.
3.如果排除是代码问题,那可能是你线程问题.jni开发中的env是每个线程都会创建一个, 其他线程不能用当前线程的env,这可能导致出现上面的问题.

解决方法:进程中没个线程都有一个env,但是只有个JavaVM .可以通过JavaVM来创建env.具体可以参考:http://blog.csdn.net/viking_xhg/article/details/78727273

###19.
1.unspecified on project app resolves to an APK archive which is not supported as a compilation dependency
2.Error:Library projects cannot set applicationId. applicationId is set to ‘package_name’ in default config.

问题原因: 存在两个Module，其中一个Module依赖另一个Module而导致；

解决方法:
1. build.gradle -> apply plugin: ‘com.android.application’ (将当前程序编译成apk) 改为 apply plugin: ‘com.android.library’ (当前程序编译为library库);
2.删除 builde.gradle — android — defaultConfig中的 applicationId “com.viking.swgetdeviceinfo” ;

###20.
remount of system failed: Permission denied
remount failed

问题原因: 挂载system失败,权限不够.

解决方法: adb root ,通过使用root权限运行remount.

###21. Error:Cause: buildToolsVersion is not specified.

问题原因: build.gralde中无buildToolsVersion 属性

解决方法: 添加 buildToolsVersion “27.0.1”

问题原因:
1. NDK版本：
32bits小机用：android-ndk32-r10b-linux-x86_64.tar.bz2
64bits小机用：android-ndk64-r10b-linux-x86_64.tar.bz2
64bits编译出来的APK在S3上面运行，会有闪退的现象.

2.造成问题的原因不是NDK的版本，而是目标平台的版本,我这运行在android 4.4上面。Android-19是在平台 头上将 Sigemptyset()(和许多其他函数)声明为内联的最后一个平台版本。因此，设备上的系统libc不包含这些功能。所以应该使用正确的目标平台来允许代码在旧的设备上运行。

解决方法: 只需要在你的应用程序中application.mk文件中添加 app_Platform：=Android-19。

###23.

2999 KB/s (8256380 bytes in 2.688s)
pkg: /data/local/tmp/app-debug.apk
Failure [INSTALL_FAILED_OLDER_SDK]

问题原因:您设备的Android版本过低，app不支持

解决方法:
Manifest中提高minSdkVersion：

###24.This Gradle plugin requires a newer IDE able to request IDE model level 3. For Android Studio this means version 3.0+

问题原因:IDE等级要为3

解决方法:在项目中的gradle.properties文件中添加

android.injected.testOnly = falsedandroid.injected.build.model.only.versioned = 3

###25.Failed to resolve :com.android.support:support-core-ui:27.0.1

问题原因: sdk版本问题

解决方法: 将build.gradle的 compileSdkVersion 23 ,targetSdkVersion 23 改成你自己的版本

###26.Error:(1, 0) Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to "6a851924f1794e8667f51b5d924eb484dbef3c9b"
Fix plugin version and sync project
Open File

问题原因: 插件太老, 降低build.gradle 去适应

解决方法:
将 classpath ‘com.android.tools.build:gradle:2.0.0-alpha3’
改成classpath ‘com.android.tools.build:gradle:1.+’

###27.Error:Failed to resolve: com.android.support:appcompat-v7:27.+
Install Repository and sync project
Show in Project Structure dialog
问题原因: 没有appcompat -v7:27.+

解决方法:将 targetSdkVersion 27版本,改成你自己的版本

###28.SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length

问题原因:File mFile = new File(dir, “FD01-” + DataTool.getFileName() + “.log”);其中的dir是一个null对象.

解决方法:将dir替换成非null对象

###29.权限申请被用户确定为永不提示
public void onRequestPermissionsResult(int requestCode,String[] permissions,int[] grantResults) {
boolean showRequestPermission = ActivityCompat.shouldShowRequestPermissionRationale(PermissionActivity.this, permissions[i]); //
if (showRequestPermission) {// 可重新申请的权限
Log.e(“PermissionActivity”, “onRequestPermissionsResult: The permissions is forbidden to be used,but this permissions can be request again. :”+permissions[i]);
} else { //禁止申请的权限
Log.e(“PermissionActivity”, “onRequestPermissionsResult: The permissions is forbidden to be used,but this permissions can’t be request again.　：” + permissions[i]);
mRequestPermissionRationale.add(permissions[i]); //被禁止使用的权限
mRequestPermission.remove(permissions[i]); //可再次申请的权限
}
}
问题原因:

解决方法:

###30. 隐藏导航栏
/*
* 隐藏虚拟按键，并且全屏
*/
protected void hideBottomUIMenu() {
//隐藏虚拟按键，并且全屏
if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else if (Build.VERSION.SDK_INT >= 19) {
//for new api versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;

问题原因:sdk要求的最低版本为16,而现在的版本为15

解决方法:将build.gradle文件中的minSdkVersion 15改成minSdkVersion 16

###32.Error:Execution failed for task ‘:app:processDebugManifest’.

问题原因:sdk要求的最低版本为16,而现在的版本为15

解决方法:将build.gradle文件中的minSdkVersion 15改成minSdkVersion 16

###33.Error:This Gradle plugin requires a newer IDE able to request IDE model level 3. For Android Studio this means version 3.0+

问题原因:Android Studio 版本个gradle版本的问题

解决方法:

1.升级android studio IDE的版本。

2.在项目的gradle.properties配置文件中加入以下这句：

android.injected.testOnly = falsed

android.injected.build.model.only.versioned = 3

###34.DrawerLayout实现侧滑菜单,出现层级问题.
出现相机展示和策划菜单会出现层级混乱问题, 一会策划菜单在相机上面, 一会策划菜单在相机下面.

问题原因:这是由于相机布局在RelativeLayout里面.

解决方法:将RelativeLayout改成Linealayout.

###35.Internal Error. Please report to https://code.google.com/p/android/issues
Android Studio 启动出现如下错误

问题原因:

android studio无法启动https://code.google.com/p/android/issues,为国外网站,需要.

解决方法:

  1. 使用软件进行

    2.最直接的方式：断开网络启动
    下次安装报：java.lang.RuntimeException: java.lang.NullPointerException…错
    只需在文件…\Android Studio\bin\idea.properties（需要对应自己的安装目录下）最后面加一行代码：
    disable.android.first.run=true 就可以完美解决问题了

AndroidRuntime: FATAL EXCEPTION: Thread-8
Process: com.viking.fd01, PID: 2826
java.lang.IllegalStateException: Can’t compress a recycled bitmap

at com.viking.activity.MainActivity$CompareLoop.loop(MainActivity.java:1109)
at com.guo.android_extend.java.AbsLoop.run(AbsLoop.java:20)

问题原因:

1.使用了已经被释放过内存的对象。

对于Bitmap：

Bitmap bitmap = 一个bitmap对象

使用过程中调用bitmap.recycle()之后,再使用bitmap就会报错。



2.图片裁剪等处理后，按照下面的写法也易报错.

public static boolean Bitmap2JpgLocal(Bitmap bmp, File fileDir, String fileName) {    if (!fileDir.exists()) {        fileDir.mkdir();    }    if (!fileName.endsWith(".jpg")) {        try {            throw new Throwable("file name end with '.jpg'!");        } catch (Throwable throwable) {            throwable.printStackTrace();        }    }    File file = new File(fileDir, fileName);    file.deleteOnExit();    try {        FileOutputStream fos = new FileOutputStream(file);        bmp.compress(Bitmap.CompressFormat.JPEG, 100, fos);        fos.flush();        fos.close();    } catch (FileNotFoundException e) {        e.printStackTrace();        return false;    } catch (IOException e) {        e.printStackTrace();        return false;    }    return true;}

解决方法:

Bitmap idcardbm = idCardPhoto.copy(Bitmap.Config.ARGB_8888,true);
通过copy出一个新的bitmap,再处理.

###38. 外置SD卡读写问题.
首先,Google在Android4.4之后将读写外置SD卡的API全部关闭了, 所以我们无法获取到外置SD路径, 只能通过反射的方式来获取外置SD卡路径

public static String[] getSecondaryStoragePath1(Context mContext) {try {StorageManager sm = (StorageManager) mContext.getSystemService(STORAGE_SERVICE);Method getVolumePathsMethod = StorageManager.class.getMethod("getVolumePaths",null); //获取需要反射的方法String[] paths = (String[]) getVolumePathsMethod.invoke(sm, null); //通过反射方法获取sd路径,paths是数据,可能有多个外部存储设置// second element in paths[] is secondary storage pathLog.e("SDCard", "getSecondaryStoragePath1: "+paths.length+""+paths[0] +"  "+paths[1]);if (paths==null||paths.length<=0){Log.e("SDCard", "getSecondaryStoragePath: storage is err!");return null;}return paths;} catch (Exception e) {Log.e("SDCard", "getSecondaryStoragePath() failed", e);}return null;}

在这之前应该先通过File mSdfile = mContext.getExternalFilesDir(null);在外置sd目录中创建 Android/data/com.viking.fd01/files 目录.

问题原因:Android4.4 Google对外置sd卡写入进行了修改.
