Question

我尝试使用以下代码从我的应用程序中卸载应用程序

     try
     {
         Log.e ( TAG, " Going to clear the application with startactivity alone  " );;
         Uri packageURI = Uri.parse("package:"+"com.example.canvas");
         Intent uninstallIntent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageURI);
         //uninstallIntent.putExtra(Intent.EXTRA_UNINSTALL_ALL_USERS, allUsers);
         startActivityForResult(uninstallIntent, REQUEST_UNINSTALL);
         Log.e ( TAG, " Cleared the applicaiton " );
     }
     catch ( Exception e )
     {
         String data = e.getMessage();
         Log.e ( TAG, " data " + data );
     }

但是我得到了一个execption而异常说

09-26 16:16:52.519: E/FActory reset(17246):  data No Activity found to handle Intent { act=android.intent.action.UNINSTALL_PACKAGE dat=package:com.example.canvas }

Answer 1

使用startActivity()

Intent intent = new Intent(Intent.ACTION_DELETE);
intent.setData(Uri.parse("package:com.example.canvas"));
startActivity(intent);

并确保您的设备上已安装该软件包。

Answer 2

而 startActivityForResult() 使用 startActivity() 喜欢这个

 Uri packageUri = Uri.parse("package:com.example.canvas");
     Intent uninstallIntent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageUri);
     startActivity(uninstallIntent);

确保您的软件包com.example.canvas已安装在您的设备中。

尝试使用开始活动获取结果时未找到Android活动
