Question

我想在纽芬兰被点击时宣布我的申请。为此,我采用了以下法典。

Uri packageURI = Uri.parse("package:"+packageName);
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
startActivity(uninstallIntent);

它给我带来了结果,但我希望在不点击“Ok”方言的“Ok” but子的情况下,直接删除“这一申请将停滞不前”。

我只想直接提出毫不拖延的申请。

Answer 1

Uninstalling without user confirmation is not allowed to 3rd party applications.

As xDragon 兹指出,一个根本的过程可以粗略地做到这一点,从字面上删除目录,让一揽子管理人处理损失,但这不是一个非常可部署的解决办法,因为AFAIK没有配备能够运行自己根子的电动装置,而这种装置在市场修改后具有风险。

Yes it is possible to uninstall a package in Android. Moreover you can also skip asking user to press OK button on uninstall screen. You can do it by using Accessibility service in Android.

public class MyAccessibilityService extends AccessibilityService {
    private static final String TAG = MyAccessibilityService.class
            .getSimpleName();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        Log.i(TAG, "ACC::onAccessibilityEvent: " + event.getEventType());

        //TYPE_WINDOW_STATE_CHANGED == 32
        if (AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED == event
                .getEventType()) {
            AccessibilityNodeInfo nodeInfo = event.getSource();
            Log.i(TAG, "ACC::onAccessibilityEvent: nodeInfo=" + nodeInfo);
            if (nodeInfo == null) {
                return;
            }

            List<AccessibilityNodeInfo> list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("com.android.settings:id/left_button");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: left_button " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }

            list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("android:id/button1");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: button1 " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }
        }

    }

    @Override
    public void onServiceConnected() {
        Log.i(TAG, "ACC::onServiceConnected: ");
    }

    @Override
    public void onInterrupt() {
        // TODO Auto-generated method stub

    }
}

您应首先研究一下“本土的。我建议你更新你使用的所有法典。

下一步是检查 PackageInstaller。这是正常的班级。您将发现<代码>uninstall 在该功能中发挥作用。坏消息是,这种需要<代码>Manifest.permission.DELETE_PACKAGES允许,而且只准许系统评估。这意味着,这不能直接提供给其他开发商。但是,我们可以使用装置所有人许可使用该装置。

这要求:

Android 6.0 or newer
Device owner permission to uninstall the package

一般来说,<代码>DELETE_PACKAGES的许可规定:

允许申请删除包裹。

不供第三方申请使用。

您收到设备所有人许可后,你可以放弃这样的一揽子计划:

String appPackage = "com.your.app.package";
Intent intent = new Intent(getApplicationContext(), 
getApplicationContext().getClass()); //getActivity() is undefined!
PendingIntent sender = PendingIntent.getActivity(getActivity(), 0, intent, 0);
PackageInstaller mPackageInstaller = 
getActivity().getPackageManager().getPackageInstaller();
mPackageInstaller.uninstall(appPackage, sender.getIntentSender());
