Market discrimination apk and debug apk

Question

There are 2 APIs, one for QA(testing and debugging) and the other for Production
I need to run QAapi for debugging (which we created using eclipse) and Productionapi when we create a market apk without changing the code. Is there any way to check if the code is using apk or apk apk currently. Or anything I can set in the manifest Thank you

Here Ant can help you. I always use Eclipse to create a debug version, and then use Ant for the release version, mainly because each of them needs a different Google Maps API API. I have two versions of main.xml, namely debugmain.xml and releasemain.xml. I changed the release target in the build.xml file and added two additional goals:

<target name="check-release_main">
    <available file="${layout.dir}/releasemain.xml" property="releasemain.present" />
</target>


<target name="-copy-rel-main" depends="check-release_main" if="releasemain.present">
    <echo message="Hit copy rel main" />
    <copy file="${layout.dir}/releasemain.xml" tofile="${layout.dir}/main.xml" overwrite="true"/>
</target>

I changed the release target dependencies depending on copy-rel-main:

<target name="release" depends="clean, -copy-rel-main....... 

and at the very end of the release target, the debug version of main.xml is copied to overwrite main.xml back into the debug version

    ......
    <echo message="Copying the debugmain.xml back to main.xml" />
    <echo message="ALWAYS LEFT IN DEBUG FROR ECLIPSE" />
    <copy file="${layout.dir}/debugmain.xml" tofile="${layout.dir}/main.xml" overwrite="true" />

</target>

You can adapt your versions to have a specific identification text or color in one of your elements to indicate which version works on your device.

You can store a boolean in your XML files along with the lines:

<resources>
  <bool name="debug">true</bool>
</resources>

and then access it in your code using this.getResources().getBoolean(R.debug)(where thisis the action or other context). Store it truemost of the time, and then set the value for it false.

You can also programmatically verify the signature of your application. I use this technique to record version information

final byte[] officalkey = {-58, -42, -44, -106, 90, -88, -87, -88, -52, -124, 84, 117, 66, 79, -112, -111, -46, 86, -37, 109};
final byte[] officaldebugkey = {-99, -69, 45, 71, 114, -116, 82, 66, -99, -122, 50, -70, -56, -111, 98, -35, -65, 105, 82, 43};

Signature raw = c.getPackageManager().getPackageInfo(c.getPackageName(), PackageManager.GET_SIGNATURES).signatures[0];
CertificateFactory cf = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) cf.generateCertificate(new ByteArrayInputStream(raw.toByteArray()));
MessageDigest md = MessageDigest.getInstance("SHA-1");
byte[] der = cert.getEncoded();
md.update(der);
byte[] digest = md.digest();


if (Arrays.equals(digest, officalkey))
    apksign = c.getString(R.string.official_build);
else if (Arrays.equals(digest, officaldebugkey))
    apksign = c.getString(R.string.debug_build);
else
    apksign = c.getString(R.string.built_by,cert.getSubjectX500Principal().getName());
