android - 无法获得提供者 - 很少在 kitkat 上崩溃

Question

一周内我在 GP 控制台收到几次崩溃报告:

java.lang.RuntimeException: Unable to get provider mypackage.MyProvider: java.lang.ClassNotFoundException: Didn't find class "mypackage.MyProvider" on path: DexPathList[[zip file "/mnt/asec/mypackage-1/pkg.apk"],nativeLibraryDirectories=[/mnt/asec/mypackage-1/lib, /vendor/lib, /system/lib]]

此外，在我的项目中添加 Firebase 功能后，我开始收到关于 com.google.firebase.provider.FirebaseInitProvider 的相同崩溃报告。

根据报告，此错误仅发生在:

Android 4.4 98,7 %

安卓 4.2 1.3%

我已经尝试了所有这些 ClassNotFoundException for a ContentProvider , 但没有结果。

这真的是一个系统错误并且每个开发人员都在处理它，还是我的错误？我真的很想停止烦人的用户。谢谢。

你的案例真的很像描述的错误 there in Android's Issue Tracker . 当用户在 apk 更新后立即启动应用程序时，您会遇到问题。

评论中有解决方法可以帮助您防止此错误:

public class DevToolsApplication extends Application {
private static final String TAG = "DevToolsApplication";

    @Override
    public void onCreate() {
        super.onCreate();
        AppLogger.i(TAG, "app start...");
        checkAppReplacingState();
    }

    private void checkAppReplacingState() {
        if (getResources() == null) {
            AppLogger.w(TAG, "app is replacing...kill");
            Process.killProcess(Process.myPid());
        }
    }
}
