这是我的广播接收器。但它没有用 你能提供任何帮助吗？ 包 com.example.uninstalldefence;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsManager;
import android.widget.Toast;

public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Receive install the radio
        if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {
            String packageName = intent.getDataString();
            System.out.println("installed:" + packageName
                    + "package name of the program");
            Toast.makeText(context.getApplicationContext(), "Added!",
                    Toast.LENGTH_LONG).show();

        }
        // Receive uninstall broadcast
        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {
            String packageName = intent.getDataString();
            System.out.println("uninstall:" + packageName
                    + "package name of the program");
            Toast.makeText(context.getApplicationContext(), "Removed!",
                    Toast.LENGTH_LONG).show();


        }
    }
}

Answer 1

Is it possible to detect Android app uninstall?

这是一个帖子。我不知道您的确切应用程序，但您可以让用户在每次启动应用程序时广播一个唯一的 ID。通过这种方式，您可以收集您拥有的“活跃”用户数量，而不是人们如何安装您的应用。

1) 如文档中所述，在安装您的应用程序之前无法运行代码。

Broadcast Action: An existing application package has been removed from the device. The data contains the name of the package. The package that is being installed does not receive this Intent. http://developer.android.com/reference/android/content/Intent.html#ACTION_PACKAGE_REMOVED
