【问题描述】：
在我的 Codenameone 项目中，我在没有源代码的情况下调用本机库（andlib）。它在调试版本中运行良好，但在使用发布选项构建时中断。应用程序启动但在调用本机代码时中断。
即使使用“android.enableProguard = false”构建提示也会失败。
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 指令是否重要？
我们使用库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“lib”文件夹中，我们也有类似的问题。它在调试模式下工作正常（扫描二维码），在发布版本中失败（扫描失败并崩溃）。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.** {*;}
有人知道吗？谢谢！
【问题讨论】：
-
您确定您正确设置了 android.enableProguard = false 并且属性中没有包含空格或其他元素。您不只是将它输入到属性文件或类似的东西中吗？对？它以什么方式失败？您是否有来自 DDMS 的崩溃日志或其他内容？
-
我在 NetBeans 中输入了 android.enableProguard 提示并且没有空格。在属性文件中它看起来像这样：“codename1.arg.android.enableProguard=false”。我已经用崩溃日志和我的 java 代码更新了我的问题。
-
您现在可以试试看是否有效吗？查看日志，您可能遇到了与支持 Lollipop 操作栏的失败尝试相关的单独问题。
-
我试过了，还是不行。错误日志中的错误是相同的。我已经用另一个使用 .cn1lib 库的示例更新了我的问题，我们遇到了同样的问题：调试版本有效，但发布失败......
-
我专门在发布模式下测试了 QRScanner。您是否按照他在此处提到的所有说明进行操作：github.com/littlemonkeyltd/QRScanner 请注意，在这种情况下，初始化程序中有一个非常明显的异常，这应该有助于跟踪。
