    Error while Launching activity

更新：不知道这是否有帮助，但下面是我在AndroidManifest.xml中声明我的启动器活动的方式：

<activity
    android:name=".LoginActivity"
    android:label="@string/app_name"
    android:screenOrientation="portrait"
    android:theme="@style/AppTheme.Launcher">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

好吧，我知道是怎么回事了。

我实际上是在为debug变体（Build>Build apk）创建一个未签名的apk。但是我必须使用（Build>Generate Signed APK）,然后从选项中选择debug变体。

此外，当在我的设备上运行项目时，gradle将生成一个未签名的APK。这样也行不通。也就是说--除非我配置signingconfigs如本答案中所解释的那样。
