Android Emulator: Process finished with exit code -1073741819

the solution that works for me was

1. find your avd folder.(If your using Windows OS, the default path is C:\Users\USER_NAME\ .android\avd\YOUR_VIRTUAL_DEVICE_NAME.avd)
2. open the file config.ini
3. find hw.gpu.mode and set it to off (hw.gpu.mode=off)
4. launch the AVD manager
5. launch your virtual device.

from https://stackoverflow.com/questions/47631771/emulator-process-finished-with-exit-code-1073741819-0xc0000005

reinstall emulator + haxm didnt worked for me only the above.

Pushy - Lightning-Fast & Highly-Reliable Push Notifications

sometimes you dont want or cant use GCM for pushes

e.g for china user  no GCM , or when you cant have Google play store - e.g. in the car .

so the alternative is jPush or Pushy  - maybe there are more...

pushy looks easy and well documented

Android studio Failed to load class dynamically

after moving to Android Studio we noticed that we get failed to load class dynamically.
via such code below:

ClassLoader cl = getClassLoader();
Class classToInvestigate = df.loadClass(className, cl);

in out case we needed to remove (disbaled) the instant run , and in the class name 

we needed to change from string ("com.xx.yy.teston") to getCanonicalName()

e.g. com.xx.yy.teston.class.getCanonicalName()

here how i disabled the instant run 

i hope you will find it useful. 

also some info you can see here

View Settings/secure/global data from Android

i was looking for a way to look into the settings.db or other secure db that exist in android , on non rooted device.
i find out this command to View the data :

adb shell content

e.g. - to see all global settings
adb shell content query --uri content://settings/global

adb shell content query --uri content://settings/system
adb shell content query --uri content://settings/secure


there is also a tool - have a look at  adb-export
