====Android Studio Ignored Files=====

  * build (and build directory if there are multiple modules in a project)
  * .idea
  * *.iml
  * local.properties
  * .DS_Store
  * .gradle
  * .cxx

====Pull APK from device====

Get the list of installed packages to determine what to pull:
  > adb shell pm list packages | grep tom
  package:com.customermobile.preload.vzw
  package:com.fanqies.tomatofn
  
With the package name, we can get the actual file name and location of the APK using:
  > adb shell pm path com.fanqies.tomatofn
  package:/data/app/com.fanqies.tomatofn-g0zd0oekwgIETU7mS62UEQ==/base.apk
  
Then pull it:
  adb pull /data/app/com.fanqies.tomatofn-g0zd0oekwgIETU7mS62UEQ==/base.apk
  
This will result in an APK file "base.apk" downloaded onto your computer. Rename it appropriately:
  mv base.apk tomato.apk

====Decompile app to android Studio====

  rm -rf $1_signed.apk
  rm -rf %1_aligned.apk 
  
  apktool b -o $1_pre.apk $1
  ~/Library/Android/sdk/build-tools/28.0.3/zipalign -f 4 $1_pre.apk $1_aligned.apk
  echo "android" | ~/Library/Android/sdk/build-tools/27.0.3/apksigner sign --ks ~/.android/debug.keystore --out $1_signed.apk $1_aligned.apk 
  rm -rf $1_pre.apk 
  rm -rf $1_aligned.apk 
  
  echo ""
  echo -n "Signed APK: "

====Debug over wifi====

Follow directions at: https://futurestud.io/tutorials/how-to-debug-your-android-app-over-wifi-without-root

Basically:

  - Connect the phone to USB
  - Make sure the device is present: "adb devices"
  - adb tcpip 5555
  - Unplug the phone from USB
  - Go to the Settings -> About phone -> Status to view the IP address of your phone.
  - adb connect <IP address of your device>:5555

Note: The TCP connection may stop occasionally and need to be restarted. Run this to continually try to restart the connection every second:

  watch -n 1 adb connect <IP address of your device>:5555
  
====Get BtSnoop logfile====

  DATE=`date +%d%m%y_%H%M%S`
  #echo $DATE
  FILENAME=btsnoop_hci.$DATE.log
  JSON_FILENAME=btsnoop_hci.$DATE.json
  #echo $FILENAME
  mkdir -p logs

  mkdir -p temp
  cd temp
  adb bugreport > BUG_REPORT.txt >/dev/null 2>/dev/null
  unzip *.zip  >/dev/null 2>/dev/null
  cp FS/data/misc/bluetooth/logs/btsnoop_hci.log ../$FILENAME >/dev/null 2>/dev/null
  cd ..
  rm -rf temp
  echo "The btsnoop logfile is logs/$FILENAME"
  tshark -T json -r $FILENAME >$JSON_FILENAME
  echo "The btsnoop JSON logfile is logs/$JSON_FILENAME"

====Galaxy S8/9/10 Get SNOOP file====

This is tested and verified working for S8, S9, S10+ Android 8.0 through to 9.1:

Input "*#9900#" (there is an asteriks in there) in the dial pad. An engineer mode menu will pop up. Click "Run DUMPSTATE/LOGCAT/". Wait. It may take several minutes for this to generate logs. Click "Copy To sdcard..." or "Copy to ext sdcard"

/sdcard/logs will contain an extensive dump of system logs /sdcard/logs/bluetooth/ will contain your timestamped btsnoop_hci_ log files
