Android 踩坑 INSTALL_FAILED_CONFLICTING_PROVIDER错误

背景介绍:

今天开发中遇到了一个错误,INSTALL_FAILED_CONFLICTING_PROVIDER错误,于是就探索了一番，这里分享一下。

1、安装&问题出现

03/08 09:53:37: Launching 'app' on API 22.
Installation did not succeed.
The application could not be installed: INSTALL_FAILED_CONFLICTING_PROVIDER

List of apks:
[0] 'F:\betatec-code\D\NQ16\app\build\outputs\apk\Kong8PcrDEF\debug\Kong8Pcr-DEF-debug_v1.0.25_debug_240308.apk'
Installation failed due to: 'Failed to commit install session 66142974 with command pm install-commit 66142974. Error: INSTALL_FAILED_CONFLICTING_PROVIDER: Package couldn't be installed in /data/app/com.bete.pcr8-2: Can't install because provider name com.bete.nq16.fileprovider (in package com.bete.pcr8) is already used by com.bete.pcr16'
Retry
Failed to launch an application on all devices

报错信息分析

两个contentProvide 互相冲突

通过搜索得知具体的原因

两个包的contentProvider 的authorities 冲突。 先安装的包的contentProvider的authorities 已经存在。后安装的包Manifest中contentProvider 的authorities 与先安装的包相同时就会报错。这个很好理解，就像应用商店的applicationid要唯一一样。

解决方式

1、修改contentProvider 的authorities的字符串值，一般设置成applicationId+自定义字符串即可（符合实际）

实际操作方式

将 authorities 中的 applicationId使用如下的方式设置

android:authorities="${applicationId}.xxxx"
