【问题描述】：

我正在尝试通过单击按钮来卸载应用程序本身，因为我的应用程序在添加了一些 Context.DEVICE_POLICY_SERVICE 时无法被用户卸载

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();

编辑：@CommonsWare cmets 解决的问题

【问题讨论】：

Uri packageUri = Uri.parse(getPackageName()); 是错误的。这需要是Uri packageUri = Uri.parse("package:"+getPackageName());。

【参考方案1】：

使用下面的代码

 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);
