解决方法:把 gradle.properties删了,重新编译。

另一个安装时的错误，安装APP成功后，打不开。

解决方法：在application标签下设置android:allowBackup=”false”

<application
        tools:replace="allowBackup"
        android:name=".MyApplication"
        android:allowBackup="false"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

PS:AS的Gradle插件默认会启用Manifest Merger Tool，若Library项目中也定义了与主项目相同的属性，则此时会合并失败，并报异常。

解决方法有以下2种：

方法1：在Manifest.xml的application标签下添加tools:replace=”allowBackup”（多个属性用”,”隔开，并且记住在manifest根标签上加入xmlns:tools=”http://schemas.android.com/tools”，否则会找不到namespace）

方法2：在build.gradle根标签上加上useOldManifestMerger true
