Question

我正在尝试通过点击按钮卸载应用程序本身，因为我的应用程序在添加了一些Context.DEVICE_POLICY_SERVICE时无法由用户卸载

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();
        }

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);
