静默安装应用

解决方案

实现静默安装应用的话需要系统权限:
在AndroidManifest.xml中添加android:sharedUserId=“android.uid.system”.
使用系统签名文件(platform.pk8、platform.x509.pem,签名文件位于build/target/product/security/目录下)对apk进行签名

在AndroidManifest.xml添加相应需要的权限

<uses-permission android:name="android.permission.INSTALL_PACKAGES" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

添加函数代码，调用函数进行应用安装

int result = installSilent("com.firefly.testslinet","/mnt/sdcard/123.apk");

前面包名是你实现静默安装的应用的包名，比如我的是testslinet 应用来静默安装/sdcrad/123.apk.那么就是 installSilent(“com.firefly.testslinet”,"/mnt/sdcard/123.apk");

有客户提出应用静默安装升级本身后希望可以自启动，下面提供自启动方案:

// AndroidManifest.xml        <receiver android:name="com.example.testfile.BootBroadcastReceiver" >            <intent-filter>                <action android:name="android.intent.action.PACKAGE_ADDED" />                <action android:name="android.intent.action.PACKAGE_REPLACED" />                <action android:name="android.intent.action.PACKAGE_REMOVED" />                <data android:scheme="package" />            </intent-filter>        </receiver>//BootBroadcastReceiver.javapackage com.example.testfile;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;import android.widget.Toast;public class BootBroadcastReceiver extends BroadcastReceiver{private static final String TAG = "sjft";public static final String EXTRA_VOLUME_STATE ="android.os.storage.extra.VOLUME_STATE";public static final int STATE_UNMOUNTED = 0;public static final int STATE_CHECKING = 1;public static final int STATE_MOUNTED = 2;public static final int STATE_MOUNTED_READ_ONLY = 3;public static final int STATE_FORMATTING = 4;public static final int STATE_EJECTING = 5;public static final int STATE_UNMOUNTABLE = 6;public static final int STATE_REMOVED = 7;public static final int STATE_BAD_REMOVAL = 8;@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString action = intent.getAction();if (action.equals("android.intent.action.PACKAGE_REPLACED")){String packageName = intent.getData().getSchemeSpecificPart();Log.v(TAG,"BootBroadcastReceiver packageName:"+packageName);if(context.getPackageName().equals(packageName)){Intent launchIntent = new Intent(context, MainActivity.class);//重新启动应用//此处如果不想写死启动的Activity，也可以通过如下方法获取默认的启动Activity//Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(packageName);intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(launchIntent);}}}
