Android项目apk无法安装write: closed

问题描述：

最近做车载项目，要调试一些硬件设备，在Win10系统下、Android Studio直接运行项目代码、install至硬件设备上，报如下错误：

又用了ADB命令手动安装apk，还是报错，如下：

即：

E:\>adb install QQM.apk
Performing Streamed Install
adb: failed to run abb_exec. Error: closed
adb: connect error for write: closed

解决：

adb shell   中运行
setprop persist.sv.enable_adb_install 1

如下：在设备上安装QQ音乐apk 。

E:\>adb shell
error: closed

E:\>adb devices
List of devices attached

E:\>adb  kill-server

E:\>adb start-server
* daemon not running; starting now at tcp:5037
* daemon started successfully

E:\>adb shell
adb.exe: no devices/emulators found

E:\>adb devices
List of devices attached
ad039675        device

E:\>adb shell   ####看这里
msmnile_gvmq:/ $ setprop persist.sv.enable_adb_install 1   ####看这里
msmnile_gvmq:/ $ exit

E:\>adb install QQM.apk
Performing Streamed Install
Success

原因：设备上的adb install开关没打开，导致apk无法install。用命令打开install权限即可。文章来源地址https://uudwc.com/A/MpY6g
