我有一个相当大的Android App项目,它引用了几个库项目.一切都很好,直到我将eclipse ADT插件升级到最新版本(v22).我当然也升级了SDK.我在eclipse中没有看到任何编译错误,但是当我在手机上运行项目时,我得到一个NoClassDefFoundError.
java.lang.NoClassDefFoundError: org.acra.ACRA
....
方舟库包含在引用库中的项目(在libs文件夹)中的一个,我可以看到它在Package Explorer中的"Android的私人图书馆",也正如我所说的,没有编译错误.该项目在没有升级ADT的其他人的计算机上运行良好.
我已经尝试了很多东西,包括但不限于:
一切都没有成功,所以我在这里真的很绝望.
如果有人能给我一个如何解决这个问题的提示,我会很高兴.
我最近将Android SDK和Eclipse ADT插件更新到最新版本.现在,当我尝试运行预先存在的Android项目时,LogCat会显示一个ClassNotFoundException.
我试图创建一个新设备但问题仍然存在.

01-04 11:06:42.302: …该项目昨天很好,但是当我今天更新Sdk工具和ADT(REV 22)时,在我运行项目时出现了"无法解析L的超类......"的错误.
我的项目使用ActionbarSherlock和SlidingMenu.
我已经尝试过了:
但他们都失败了.
整个Logcat如下:

05-17 06:53:50.207: D/dalvikvm(949): VFY: …我有一个Android应用程序,我在其中添加了一个枚举:
public enum RootNavigationOption {
HOME(R.string.home, R.drawable.ic_home), SETTINGS(R.string.settings, R.drawable.ic_settings), LOGOUT(
R.string.logout_label, R.drawable.ic_logout);
private int navigationOptionLabelResId;
private int navigationOptionImageResId;
private RootNavigationOption(int navigationOptionLabelResId, int navigationOptionImageResId) {
this.navigationOptionLabelResId = navigationOptionLabelResId;
this.navigationOptionImageResId = navigationOptionImageResId;
}
public int getNavigationOptionLabelResId() {
return navigationOptionLabelResId;
}
public int getNavigationOptionImageResId() {
return navigationOptionImageResId;
}
public static int getValuePosition(RootNavigationOption filterOption) {
int idx = 0;
for (RootNavigationOption navigationOptionIter : values()) {
if (navigationOptionIter.equals(filterOption)) {
return idx;
}
idx++;
}
return 0;
}
}
我把这个枚举放在了几个意图包中,以便与我的主要活动进行交流.我的enum解决方案中已经有一个这样的,这不会导致任何问题.但是,当我使用这个新enum的定义运行我的应用程序时,它会立即崩溃:
java.lang.RuntimeException: Parcelable …
