一、Android8.0之前的版本

在Android8.0之前，可以通过注册静态广播来监听应用安装或者删除的广播

如下是在AndroidManifest.xml中注册静态广播的一段代码

        <receiver android:name=".MyReceiver">
            <intent-filter>
                <action android:name="android.intent.action.PACKAGE_ADDED" />
                <action android:name="android.intent.action.PACKAGE_REMOVED" />
                <action android:name="android.intent.action.PACKAGE_REPLACED" />

                <data android:scheme="package" />
            </intent-filter>
        </receiver>

<intent-filter>

</intent-filter>

</receiver>

唯一需要注意的是，有一个android:scheme属性是必须的，否则收不到广播

二、Android8.0之后的版本

Android8.0之后很多静态广播不能用了，想要接收应用安装、覆盖安装和删除的广播，需要动态注册广播。

代码如下：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
        filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
        filter.addAction(Intent.ACTION_PACKAGE_REPLACED);
        filter.addDataScheme("package");
        registerReceiver(mReceiver, filter);
    }

    @Override
    protected void onDestroy() {
        unregisterReceiver(mReceiver);
        super.onDestroy();
    }

    BroadcastReceiver mReceiver = new BroadcastReceiver(){

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            Toast.makeText(MainActivity.this, action, Toast.LENGTH_SHORT).show();
        }
    };
}

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);

filter.addAction(Intent.ACTION_PACKAGE_REMOVED);

filter.addAction(Intent.ACTION_PACKAGE_REPLACED);

filter.addDataScheme("package");

registerReceiver(mReceiver, filter);

}

@Override

protected void onDestroy() {

unregisterReceiver(mReceiver);

super.onDestroy();

}

BroadcastReceiver mReceiver = new BroadcastReceiver(){

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

Toast.makeText(MainActivity.this, action, Toast.LENGTH_SHORT).show();

}

};

}

需要注意的是，必须使用这句代码filter.addDataScheme(“package”);来指定DataScheme
