我的清单：

        android:name=".MyApplication"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:logo="@drawable/title_logo"
        android:theme="@style/Theme.App" >

        <!-- Tablet Starts -->

        <activity
            android:name=".ui.StartActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:label="@string/app_name"

            </intent-filter>
        </activity>
</application>

我已经选中的复选框 Android的私人图书馆和 Android的依赖在订单和出口标记。我用 proguard.cfg 包含 -keep公共类*扩展android.app.Application 。我出口在皮棉错误检查时，未选中的复选框运行全面检查。请帮我拿到签名的apk文件，没有任何问题。谢谢你。

I have selected check boxes Android Private Libraries and Android Dependencies under Order and Exports tag. And I used proguard.cfg it contains -keep public class * extends android.app.Application. I unselected check box Run full check when exporting under Lint Error Checking. Please help me to get signed apk without any issue. Thank You.

推荐答案

我有同样的问题后，不能minifyEnabled真正解决了这一问题。如果只存在于签署APK的问题。检查buildtypes松开module.gradle

I had the same problem after disabling minifyEnabled true fixed the problem. if the problem only exist on signed apk. check buildtypes release on module.gradle

 buildTypes {
    release {
     // minifyEnabled true

    }
}
