卸载应用程序本身按钮

Question

我试图卸载应用程序本身上的按钮的点击，因为我的应用程序是无法被用户卸载时，它已经增加了一些Context.DEVICE_POLICY_SERVICE

try { 
      try { 
       ComponentName devAdminReceiver = new ComponentName(mContext, AdminReceiver.class); 
       DevicePolicyManager dpm = (DevicePolicyManager) mContext.getSystemService(Context.DEVICE_POLICY_SERVICE); 
       dpm.removeActiveAdmin(devAdminReceiver); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 

      new Handler().postDelayed(new Runnable() { 
       @Override 
       public void run() { 
        try { 
         Uri packageUri = Uri.parse(getPackageName()); 
         Intent uninstallIntent = 
           new Intent(Intent.ACTION_DELETE, packageUri); 
         uninstallIntent.putExtra(Intent.EXTRA_RETURN_RESULT, false); 
         //new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageUri); 
         startActivity(uninstallIntent); 
        } catch (Exception e) { 
         e.printStackTrace(); 

         Uri packageURI = Uri.parse(getPackageName()); 
         Intent uninstallIntent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageURI); 
         startActivity(uninstallIntent); 
        } 
       } 
      }, 1200); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     }

使用以下代码

Uri packageUri = Uri.parse("package:"+getPackageName()); 
         Intent uninstallIntent = 
           new Intent(Intent.ACTION_DELETE, packageUri); 
         uninstallIntent.putExtra(Intent.EXTRA_RETURN_RESULT, false); 
         //new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageUri); 
         startActivity(uninstallIntent);
