android studio调试c/c++代码

一、Debug调试效果

二、配置JNI调试环境

2.1 配置build.gradle

build.png

只需配置android标签节点下的buildTypesbuildTypes{       debug{        jniDebuggable true        jniDebuggable = true    }}

2.2 配置AndroidManifest属性

android:debuggable="true"

2.3 配置Run/Debug configurations

选择run下拉item，选Edit Configurations,弹出配置窗体
点击➕新建 configuraionts，选android native条目
配置下native执行的名称如：hellojniNative.
选择真机或模拟器调试.

三、code

源码取的是ndk目录下hellojni demo，可以自行去获取

3.1 java code

public native String  stringFromJNI();    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);                /* Create a TextView and set its content.         * the text is retrieved by calling a native         * function.         */        final TextView  tv = new TextView(this);        tv.setText("点击调用方法");        tv.setTextSize(100);        tv.setClickable(true);        tv.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {//              start(tv);                tv.setText(stringFromJNI());            }        });        setContentView(tv);    }

3.2 natvie code

jstringJava_com_example_hellojni_HelloJni_stringFromJNI( JNIEnv* env,                                                  jobject this ){#if defined(__arm__)  #if defined(__ARM_ARCH_7A__)    #if defined(__ARM_NEON__)      #if defined(__ARM_PCS_VFP)        #define ABI "armeabi-v7a/NEON (hard-float)"      #else        #define ABI "armeabi-v7a/NEON"      #endif    #else      #if defined(__ARM_PCS_VFP)        #define ABI "armeabi-v7a (hard-float)"      #else        #define ABI "armeabi-v7a"      #endif    #endif  #else   #define ABI "armeabi"  #endif#elif defined(__i386__)   #define ABI "x86"#elif defined(__x86_64__)   #define ABI "x86_64"#elif defined(__mips64)  /* mips64el-* toolchain defines __mips__ too */   #define ABI "mips64"#elif defined(__mips__)   #define ABI "mips"#elif defined(__aarch64__)   #define ABI "arm64-v8a"#else   #define ABI "unknown"#endif    return (*env)->NewStringUTF(env, "Hello from JNI !  Compiled with ABI " ABI ".");}
