＞adb: error: failed to copy ‘xx.apk‘ to ‘/system/app/test1.apk‘:remote Permission denied

system没有读写权限

C:\Users\Administrator>adb push test1.apk /system/app/

adb: error: failed to copy 'test1.apk' to '/system/app/test1.apk':

remote Permission denied

test1...ile pushed, 0 skipped. 58.8 MB/s (2806241 bytes in 0.046s)

adb push失败，缺少系统权限，push到系统盘，但是系统只读，可以添加系统权限再push

解决办法

adb root;adb remount

C:\Users\Administrator>adb root
restarting adbd as root

C:\Users\Administrator>adb remount
remount succeeded

C:\Users\Administrator>adb push test1.apk /system/app/

test1...ile pushed, 0 skipped. 62.5 MB/s (2806241 bytes in 0.043s)

adb remount 重新挂载system，即读写权限获取

adb shell mount -o rw,remount /system

C:\Users\Administrator>adb shell 
mount  -o  rw,remount /system

C:\Users\Administrator>adb push test1.apk /system/app/

test1...ile pushed, 0 skipped. 62.5 MB/s (2806241 bytes in 0.043s)

/syetem获取读写权限
