In my Codenameone project, I am calling native libraty (andlib) without source code. It works good when it is in debug version but when it breaks when it's built with release option. Application starts but it breaks when native code is called.
It fails even if "android.enableProguard = false" build hint is used.
my java code is(it breaks on the last line of code):
final android.app.Activity ctx = com.codename1.impl.android.AndroidNativeUtil.getActivity();
Intent intent = new Intent(ctx, Pdf417ScanActivity.class);
Pdf417MobiSettings sett = new Pdf417MobiSettings();
sett.setPdf417Enabled(true);
sett.setNullQuietZoneAllowed(true);
sett.setDecodeUSDriverLicenseData(true);
sett.setQrCodeEnabled(true);
sett.setDontShowDialog(true);
sett.setRemoveOverlayEnabled(true);
intent.putExtra(Pdf417ScanActivity.EXTRAS_SETTINGS, sett);
System.out.println("----- before startActivityForResult");
com.codename1.impl.android.AndroidNativeUtil.startActivityForResult(intent, new IntentResultListener() {
This is error log from logcat:

Instructions for using ProGuard with this native library are:
If you are using ProGuard, add the following lines to your application proguard-project.txt file
-keep class net.photopay.** { *; }
-keepclassmembers class net.photopay.** {
*;
}
-keep class mobi.pdf417.** { *; }
-keepclassmembers class mobi.pdf417.** {
*;
}
-dontwarn android.hardware.**
-dontwarn android.support.v4.**
Should these ProGuard instrucrions matter if I set "android.enableProguard = false" ?
We have created a simple test project with the library QRScanner.cn1lib (link is from the codename website). QRScanner.cn1lib is included in our project "lib" folder and we have a similar problem. It works fine in debug mode(scans qr code), and fails in release version(fails to scan and crashes). Build hit "android.enableProguard" is set to "false". Here is error log:

This is the java code:
protected void onMain_ButtonScanAction(final Component c, ActionEvent event) {
Form f = c.getComponentForm();
final TextArea tra = findTextAreaResult(f);
tra.setText("Wait for result ...");
System.out.println("---- before QRScanner.scanQRCode");
QRScanner.scanQRCode(new ScanResult() {
public void scanCompleted(String contents, String formatName, byte[] rawBytes) {
System.out.println("---- scanCompleted");
System.out.println("---- contents=" + contents);
tra.setText(contents);
}
public void scanCanceled() {
System.out.println("---- scanCompleted");
Dialog.show("QR Code", "scan Canceled", "OK", null);
}
public void scanError(int errorCode, String message) {
System.out.println("---- scanCompleted");
Dialog.show("QR Code", "scan Error", "OK", null);
}
});
}
}
these are keys(from properties file) required by QRScanner.cn1lib:
codename1.arg.android.xapplication=<activity android\:name\="com.dm.zbar.android.scanner.ZBarScannerActivity" android\:screenOrientation\="landscape" android\:label\="@string/app_name" />
codename1.arg.android.xpermissions=<uses-permission android\:name\="android.permission.CAMERA"/><uses-feature android\:name\="android.hardware.camera" android\:required\="false"/>
codename1.arg.android.proguard.Keep=-keep class net.sourceforge.zbar.** {*;}
Does anyone have any clue? Thanks!
