adb to pull an installed app

no root needed How do I get an apk file from an Android device?

adb shell pm list packages -f -s

-f is to get file location for packages; -s is to show system apps

Result is like package:/data/app/XX.XX.XX==/base.apk=YY.YY.YY. Use adb pull to get this apk even though /data is restricted.

Android 4.4 僅當編譯adb時有ALLOW_ADBD_ROOT宏，纔可能有高權限。

 

• ro.debuggable：爲1時，允許adb root，然後能adb remount，從而有高權限。如果編譯時不定義ALLOW_ADBD_ROOT，則雖然能adb root，但是不能adb remount，仍沒有高權限。
• ro.secure：爲0時，允許adb remount，改變取值後，adb調試要重新打開才能生效。
• ro.adb.secure：決定是否在使用adb時需要詢問用戶進行鑑權。
• ro.allow.mock.location：是否允許模擬地址。
