Question

在我的Codenameone项目中，我在没有源代码的情况下调用本机libraty（andlib）。它在调试版本中运行良好，但在它使用release选项构建时会中断。应用程序启动但在调用本机代码时会中断。

即使＆＃34; android.enableProguard = false＆＃34;它也会失败使用构建提示。

我的java代码是（它在最后一行代码中断）：

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() {

这是来自logcat的错误日志：

12-04 09:50:21.417: E/dalvikvm(31608): Class lookup Ljava/lang/NoClassDefFoundError; attempted while exception Ljava/lang/ExceptionInInitializerError; pending

将ProGuard与此本机库一起使用的说明如下：

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.**

如果我设置＆＃34; android.enableProguard = false＆＃34;这些ProGuard指令是否重要？？

我们已经使用库QRScanner.cn1lib创建了一个简单的测试项目（链接来自代号网站）。 QRScanner.cn1lib包含在我们的项目＆＃34; lib＆＃34;文件夹，我们有类似的问题。它在调试模式下工作正常（扫描qr代码），在发布版本中失败（无法扫描和崩溃）。构建命中＆＃34; android.enableProguard＆＃34;设置为＆＃34; false＆＃34;。这是错误日志：

这是java代码：

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); 
                    }
                });
        }
}

这些是QRScanner.cn1lib所需的密钥（来自属性文件）：

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.** {*;}

有没有人有任何线索？谢谢！

似乎enableProguard最近更新了Android SDK，我们正在尝试修复它，但与此同时我建议使用更具体的proguard条件。
