Android studio 报错：Manifest merger failed xxx

如果是提示建议添加 'tools:replace="android:allowBackup"'

只需修改application下属性为

android:name=".YwApplication"
android:allowBackup="true"
android:icon="@mipmap/txlogo"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
tools:replace="android:icon, android:label, android:theme"
android:theme="@style/Theme.AppCompat.Light.NoActionBar"

rebuild即可
