In business, I want to take a look at the competing company’s apps ~~ and see the source code, so I leave it as a memorandum.
Download the Android application installed on the device
# Check if the connection between the PC and device is established $ adb devices # Search target package $ adb shell pm list packages -f | grep [keyword to download]
If you enter the company name or the name of the application, the keyword to download is usually caught.
# Example $ adb shell pm list packages -f | grep yamachita0109 package:/data/app/com.yamachita0109.voice-Q6HZbU2pgLu4T3FCQg74kg==/base.apk=com.yamachita0109.voice
The standard output value is decomposed.
|APK save path||/data/app/com.yamachita0109.voice-Q6HZbU2pgLu4T3FCQg74kg==/|
|APK file name||base.apk|
# Specify APK save path $ adb pull [APK save path]
# Example $ adb pull /data/app/com.yamachita0109.voice-Q6HZbU2pgLu4T3FCQg74kg==/ /data/app/com.yamachita0109.voice-Q6HZbU2pgLu4T3FCQg74kg==/: 1 file pulled. 31.4 MB/s (9086342 bytes in 0.276s) # APK file has been downloaded $ ls com.yamachita0109.voice-Q6HZbU2pgLu4T3FCQg74kg\=\=/ base.apk lib
Decompile the APK file
git clone https://github.com/skylot/jadx.git cd jadx ./gradlew dist
JDK 8 or higher must be installed:
So be careful.
# OK through Path $ build/jadx/bin/jadx --log-level error [APK file path]
A folder is created with the APK file name. The source code is included in it, so you can use it as a reference.
