If you often copy your Android project to another you have to using function for obtaining varied information about package.
This code show how get package name in Android application as string:
This code show how get package name in Android application as string:
Context context = getContext(); // this.getContext(); getApplicationContext(); etc.
String sPackName = context.getPackageName();
Goto in for cycle Java example source code.

You can get list by class Build
For example:
List of Build class getting from emulator:
"BOARD=unknown
BRAND=generic
CPU_ABI=armeabi
DEVICE=generic
DISPLAY=sdk-eng 2.1-update1 ECLAIR 35983 test-keys
FINGERPRINT=generic/sdk/generic/:2.1-update1/ECLAIR/35983:eng/test-keys
HOST=android-test-13.mtv.corp.google.com
ID=ECLAIR
MANUFACTURER=unknown
MODEL=sdk
PRODUCT=sdk
TAGS=test-keys
TIME=1273161972000
TYPE=eng
USER=android-build
"
For example:
if(Build.MANUFACTURER.equals("unknown")) {
// Emulator
}
List of Build class getting from emulator:
"BOARD=unknown
