Question

Senerio就像这样，我的带有Version.1的应用程序出现在 priv-app 文件夹中，它运行正常，现在我用新的Version.2更新它。应用程序从 LauncherActivity.java 开始，无故障运行。在我的程序中某处发生了 NullPointerException 崩溃，然后App退出，当我尝试打开它时开始崩溃。我正在使用外部库并检查Order和Export中的所有库 PackageName是 com.example 这是LOG -

            <category android:name="android.intent.category.LAUNCHER" />

    </activity>
</application>
