Codenameone Android调试工作发布失败-本机

Question

在我的Codenameone项目中，我正在调用没有源代码的本机libraty（andlib）。 当它处于调试版本时，它工作良好，但是当使用发布选项构建它时，它中断了。 应用程序启动，但是在调用本机代码时会中断。

即使使用“ android.enableProguard = false”构建提示，它也会失败。

我的Java代码是（它在代码的最后一行中断）：

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“ android.enableProguard = false”，这些ProGuard指令是否应该起作用？

我们使用QRScanner.cn1lib库（链接来自代号网站）创建了一个简单的测试项目。 QRScanner.cn1lib包含在我们的项目“ lib”文件夹中，我们有类似的问题。 它在调试模式下正常工作（扫描二维码），在发行版中失败（无法扫描并崩溃）。 构建命中“ android.enableProguard”设置为“ false”。 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所需的键（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.** {*;}

有人有任何线索吗？ 谢谢！

似乎enableProguard在Android SDK的最新更新中中断了，我们正在尝试对其进行修复，但与此同时，我建议使用更具体的proguard条件。
