Android quick tips to remove and install an APK

Pre-req

• Need to have ADB installed

Our aim is to install an old version of Music.apk onto a custom version. So the steps are like…

1. adb devices     #(shows list of devices attached)


2. adb remount   #mounts the directory for writing.


3. adb shell pm list packages -f     #Lists all apps (.apk’s) you have installed on phone


4. adb shell rm /system/app/Music2.apk                #Removes the apk.


5. adb push C:/pgms/“Music.apk” /system/app    #Specify full directory


6. adb shell pm list packages -f         #Confirm Music.apk  installation


7. exit
