在我的Codenameone項目中，我調用沒有源代碼的本機libraty（andlib）。它在調試版本中運行良好，但在使用發佈選項構建時會中斷。應用程序啓動，但在調用本機代碼時會中斷。Codenameone Android調試工程發佈失敗 - 原生
即使使用「android.enableProguard = false」構建提示，它也會失敗。
我的Java代碼（它打破上的最後一行代碼）：
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() {
這是錯誤日誌從logcat的：

說明使用ProGuard本機庫是：
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.**
如果我設置了「android.enableProguard = f」，這些ProGuard指令是否應該重要別的「？
我們已經創建了一個簡單的測試項目與庫QRScanner.cn1lib（鏈接是從代號網站）。 QRScanner.cn1lib包含在我們的項目「lib」文件夾中，我們也有類似的問題。它在調試模式（掃描qr代碼）下工作正常，並且在發佈版本中失敗（無法掃描和崩潰）。構建命中「android.enableProguard」設置爲「false」。下面是錯誤日誌：

這是java代碼：
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);
}
});
}
}
這些鍵（從屬性文件）的要求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.** {*;}
沒有人有任何線索？謝謝！
您確定您正確設置了android.enableProguard = false，並且沒有在屬性中包含空格或其他元素。你不只是把它輸入到屬性文件或類似的東西？對？它以什麼方式失敗？你有DDMS的崩潰日誌還是要繼續下去？ – 2014-12-04 07:25:22
我已經在NetBeans中輸入了android.enableProguard提示，並且沒有空格。在屬性文件中，它看起來像這樣：「codename1.arg.android.enableProguard = false」。我用崩潰日誌和我的java代碼更新了我的問題。 – 2014-12-04 09:15:30
你現在可以試試看看它是否有效？查看日誌可能會遇到與支持Lollipop操作欄失敗嘗試相關的單獨問題。 – 2014-12-04 18:09:45
