AndroidTampering

AndroidTampering is a library that provides an extra layer of security to your Android application. This library protects your application against simple tampering attacks. Please note that this protection methods can also be hacked. So, besides the tampering protection, don't forget to add all the other security recommendations like ProGuard, patching the Security Provider with ProviderInstaller...

Check this talk from Scott Alexander-Bown to learn more about android security for applications.

Code

Certificate signature

Get your certificate signature:

// This method will print your certificate signature to the logcat.
AndroidTamperingProtectionUtils.getCertificateSignature(context);

**

Please note that this certificate signature contains a \n at the end.

Add tampering protection

AndroidTamperingProtection androidTamperingProtection = new AndroidTamperingProtection.Builder(context, "yweraaaaaaaaggggDfsa6egkjjI\n")
    .installOnlyFromPlayStore(true) // By default is set to false.
    .build();

if (!androidTamperingProtection.validate()) {
    Toast.makeText(this, "The application is compromised! Contact the application provider.", Toast.LENGTH_LONG).show();

    finish();
}
