android - Does our Apps load all classes in the included library files? -

-

in android applications include many library files such google-play-services-lib , facebook-sdk etc. never use features , classes libraries, question when .apk file gets created classes included or classes use included in our application? if yes there way can around that? ie can remove or avoid inclusion of classes?

thank you...

you should keep android application small possible. therefore should include classes in jars need.

it better obfuscate code using proguard.

proguard java class file shrinker, optimizer, obfuscator, , preverifier. the shrinking step detects , removes unused classes, fields, methods, , attributes. optimization step analyzes , optimizes bytecode of methods

obfuscation secures code extent.

to enable proguard in project, edit project.properties

# project target. proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt target=google inc.:google apis:16 android.library.reference.1=../actionbarsherlock

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
