[移动开发]解决Failure [INSTALL_FAILED_TEST_ONLY]

运行一个新项目，报错如下:

Installation did not succeed.
The application could not be installed: INSTALL_FAILED_TEST_ONLY

List of apks:
[0] '/Users/juwuguo/AndroidStudioProject/RecyclerTabLayout-master/demo/build/outputs/apk/debug/demo-debug.apk'
Installation failed due to: 'INSTALL_FAILED_TEST_ONLY'

网上一顿查找，大多都是通过修改AndroidManifest.xml 中android:testOnly="true" 改成 android:testOnly="false"，或者直接去掉。

又或者adb命令:

adb push *.apk /tmp

adb shell pm install -t /tmp/*.apk

通通不好使。

解决办法:

根目录下gradle.properties文件里，加上一句

android.injected.testOnly=false

运行，OK。收工，记录一下。?
