我使用 LeakCanary，不幸的是发生了泄漏，这是 logcat:

这是我的调试 Activity
@Override
protected void onCreate(Bundle savedInstanceState) {
LeakCanary.install(getApplication());
setContentView(R.layout.activity_debugging);
activityTV = (TextView) findViewById(R.id.debugText);
LocalBroadcastManager.getInstance(getApplicationContext()).registerReceiver(screenReceiver, new IntentFilter("com.ponnex.justdrive.ActivityRecognitionIntentService"));
}
private BroadcastReceiver screenReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String activity = intent.getStringExtra("Activity");
updateUI(activity);
}
};
public static void updateUI(String activity) {
activityTV.setText(activity);
}
我一直在检查我的 Activity 并追踪它，但我不知道如何解决这个问题，有什么帮助吗？ :D
如果您需要我的 Activity 代码的更多信息，我很乐意在此处添加或发布它们；)

我还从另一个引用 snackbar( Snackbar by Nispok ) 的 Activity 中泄漏

最佳答案
需要调用LocalBroadcastManager.unregisterReceiver方法。
LocalBroadcastManager.getInstance(getApplicationContext()).unregisterReceiver(screenReceiver)
