Android笔记--卸载

         这一节主要简单总结一下Android里面常见的卸载方式，如下:

方式1:

 private void executeUnInstall(String packageName) {
        try {
            Intent intent = new Intent(this, this.getClass());
            PendingIntent sender = PendingIntent.getActivity(this, 0, intent, 0);
            PackageInstaller mPackageInstaller = getPackageManager().getPackageInstaller();
            mPackageInstaller.uninstall(packageName, sender.getIntentSender());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

方式2：

 private void executeUnInstall(String  packageName)  {
        try {
            PackageDeleteObserver deleteObserver = new PackageDeleteObserver();
            PackageManager pm = this.getPackageManager();
            Class[] unInstallTypes = new Class[] {String.class, IPackageDeleteObserver.class, int.class};
            Method unInstallMethod = pm.getClass().getMethod("deletePackage", unInstallTypes);
            unInstallMethod.invoke(pm, new Object[] {packageName, deleteObserver, 0});
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
 
    class PackageDeleteObserver extends IPackageDeleteObserver.Stub {
 
        public void packageDeleted(String packageName, int returnCode) throws RemoteException {
            LogUtils.i(" -- packageDeleted --->packageName:" + packageName);
        }
    }
 
    private void registerUnInstallReceiver() {
        unInstallBroadCastReceiver = new UnInstallBroadCastReceiver();
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED);
        intentFilter.addDataScheme("package");
        registerReceiver(unInstallBroadCastReceiver,intentFilter);
    }
 
    public class  UnInstallBroadCastReceiver extends BroadcastReceiver {
 
        @Override
        public void onReceive(Context context, Intent intent) {
            if(intent.getAction() == Intent.ACTION_PACKAGE_REMOVED) {
            }
        }
    }

单独建立一个文件:
包名:
package android.content.pm;
 
public interface IPackageDeleteObserver extends android.os.IInterface {
public abstract static class Stub extends android.os.Binder implements android.content.pm.IPackageDeleteObserver {
 
public Stub() {
throw new RuntimeException("Stub!");
}
public static android.content.pm.IPackageDeleteObserver asInterface(android.os.IBinder obj) {
 
throw new RuntimeException("Stub!");
}
 
public android.os.IBinder asBinder() {
 
throw new RuntimeException("Stub!");
 
}
 
public boolean onTransact(int code, android.os.Parcel data, android.os.Parcel reply, int flags)
 
throws android.os.RemoteException {
 
throw new RuntimeException("Stub!");
}
}
 
public abstract void packageDeleted(java.lang.String packageName, int returnCode)
throws android.os.RemoteException;
}

方式3:

   public static void uninstallByShell(String pkgName) {
        try {
            //  adb shell pm uninstall com.xxx.xxx
            Runtime.getRuntime().exec("pm uninstall " + pkgName);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

方式4:

 public static void uninstallByIntent(Context context, String pkgName) {
        Intent intent = new Intent(Intent.ACTION_DELETE);
        intent.setData(Uri.parse("package:" + pkgName));
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(intent);
  }
