我从事一个项目已经很长时间了。
最近，我开始在应用程序启动时遇到ANR问题。
实际上，由于从未调用App.onCreate()方法，因此应用程序甚至无法启动。据我所知，在此之前唯一被调用的是任何onCreate()的{{1}}方法。所以我从清单文件中删除了它们，但问题仍然存在。 App。ContentProvider仍未调用。
以下是一些其他详细信息：

根据日志public class FCMIDService extends FirebaseInstanceIdService{
private static final String TAG = "FCMIDService";
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is called when the InstanceID token
* is initially generated so this is where you would retrieve the token.
*/
@Override
public void onTokenRefresh() {
CLog.d(TAG, "FCM id received");
// Get updated InstanceID token.
String token = FirebaseInstanceId.getInstance().getToken();
//Do something with the token
//...
}
@Override
public void onCreate() {
Log.d("atf", "on create here called");
super.onCreate();
}
}
属于 FCMIDService 类，但这没有任何意义。当我调试应用程序时，永远不会调用ANR方法。那么如果onCreate()从未执行过，怎么会掉在那里？
另一个重要提示： 当我将代码回滚到以前的工作版本（通过SVN）时，相同的问题仍然存在，这使我认为我使用的一个库的存储库已更改。
EDIT2：
经过一些试验，我发现问题是由ANR引起的。
当我删除行
Facebook integration及其所有与之相关的Java代码，"implementation 'com.facebook.android:facebook-android-sdk:[4,5)'"
消失了。
我无法辞职于Facebook实施，因此我更换了
ANR与
"implementation 'com.facebook.android:facebook-android-sdk:[4,5)'"
根据https://mvnrepository.com/artifact/com.facebook.android/facebook-android-sdk/3.19.0。但这没用。
有任何解决方法的想法吗？
答案 0 :(得分：3)
问题出现在Facebook存储库中。 我只是更改了app.gradle文件中的一行代码： 来自
implementation 'com.facebook.android:facebook-android-sdk:[4,5)'
到
api 'com.facebook.android:facebook-share:4.36.0'
就是这样，没有其他更改。
这就是正在发生的事情： 由于我在依赖性声明 [4,5）中使用了版本范围，因此gradle会自动将Facebook库更新为最新版本（当前为4.36.0）。而且Facebook最近确实更新了他们的存储库，那是我开始遇到问题的时候。
解决方案是不实施其完整的sdk（com.facebook.android:facebook-android-sdk:[4,5）），而仅实施其中的一部分（com.facebook.android ： facebook-share ：4.36.0），由于我现在没有版本范围，因此，如果Facebook决定再次进行更新，我应该不会有任何问题。
显然，最新的Facebook库中的某些内容开始与某些内容发生冲突，或者他们只是干得很烂。
答案 1 :(得分：0)
在调用super.onCreate()之前不要放置语句；这是非法的，并且很有可能是您从背景ANR获得Service的原因，而背景UiThread几乎无法运行-并且FirebaseInstanceIdService已过时，因此应完全替换。
答案 2 :(得分：-1)
当阻塞UI线程的时间过长时，基本上会发生这种情况。因此，请检查您最近执行阻止UI线程操作的代码。有关ANR的更多信息，请访问： https://developer.android.com/topic/performance/vitals/anr
