In Code:

final PackageManager packageManager = getPackageManager();

try {
    final ApplicationInfo applicationInfo = packageManager.getApplicationInfo(getPackageName(), 0);
    if ("com.android.vending".equals(packageManager.getInstallerPackageName(applicationInfo.packageName))) {
        // App was installed by Play Store
    }
} catch (final NameNotFoundException e) {
    e.printStackTrace();
}

"com.android.vending" tells you it came from the Google Play Store. I'm not sure what the Amazon Appstore is, but it should be easy to test using the above code.

Via ADB:

adb shell pm dump "PACKAGE_NAME" | grep "vending"

Example:

adb shell pm dump "com.android.chrome" | grep "vending"

installerPackageName=com.android.vending
