权限被拒绝导致“安装因APK文件无效而失败”

Question

When I try to run my app on my Nexus 4 running 4.2.1, I kept on getting this error in eclipse:

[2012-12-22 19:30:51 - Rhiokai] Installation failed due to invalid APK file!
[2012-12-22 19:30:51 - Rhiokai] Please check logcat output for more details.
[2012-12-22 19:30:51 - Rhiokai] Launch canceled!

I tired pushing and installing via adb but it didn't work either. I figured out that it was because of this message in Logcat:

12-22 19:37:29.326: W/zipro(7371): Unable to open zip '/data/local/tmp/Rhiokai.apk': Permission denied
12-22 19:37:29.326: D/asset(7371): failed to open Zip archive '/data/local/tmp/Rhiokai.apk'

Any ideas on how to fix this issue?

Answer 1

I started receiving this error after rooting my phone.

The reason for "permission denied" is that apk files uploaded to /data/local/tmp had the -rw----- permission and owned by root, and the installer process obviously did not have permissions to read any such file.

I never found a solution, but have a workaround that satisfies me. I have simply moved/symlinked the tmp directory to the SD card. Since SD card is formatted as FAT, it does not have owners/permissions and all files created there are always readable by everyone.

# cd /data/local
# mv tmp tmp-old # (or simply rm -rf tmp)
# mkdir /mnt/sdcard/tmp
# ln -s /mnt/sdcard/tmp ./tmp

What operating system are you using? Perhaps your folder is lacking the appropriate permissions?

如果您已在设备上使用具有相同程序包名称的已签名版本的应用程序，则可能需要在重新安装之前将其卸载（除非您要再次签名，然后将该已签名的应用程序上载到设备）。
