我从稳定的频道更新到Android Studio 2.1.我一做到这一点,我就得到了我的登录类的ClassNotFoundException,它在清单中声明了很长时间.在更新之前,我的应用程序编译正常.

我刚刚将Android SDK,ADT和Proguard升级到最新版本.

我的项目编译构建并在调试模式下运行良好,但是一旦我尝试导出它的签名版本APK,我就会从Eclipse控制台上的导出向导收到错误而没有任何错误日志消息!*

如果我尝试通过Window->Show View->Error Log所有查看错误日志,我看到更多相同:

我不知道该怎么办,因为Eclipse和Proguard都不会暗示问题是什么.

我的项目在最近的升级之前一直很好.没有构建警告.没有棉绒警告!

我正在使用Android的标准配置文件${sdk.dir}\tools\proguard\proguard-android.txt:

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

-dontoptimize
-dontpreverify

-keepattributes *Annotation*

我有一个华硕Eee Tab(Transformer Prime TF201 Android v4.1.1).我正在阅读关于Geofencing的API并将下面的示例应用程序下载到我的设备=> http://developer.android.com/training/location/geofencing.html.但是当我打开它时它会终止.

我在AndroidManifest.xml文件中设置了目标sdk = 16

我最近刚收到设备"Desire HD(ace)"的错误报告,我无法为我的生活重新创建.我查看了Here1和Here2,但它似乎不能帮助我解决我的问题,或者我只是不理解这一点,以了解这是否是我的问题的解决方案.

我创建了一个 Android主库项目，在其中创建了一个自定义视图类：

package com.my.android.library.layout;

public class CustomView extends View {
...

我还为我定义了styleableCustomView：

<?xml version="1.0" encoding="utf-8"?>
<resources>
     <declare-styleable name="CustomView">
        <attr name="title_text" format="string" />
    </declare-styleable>
</resources>

由于我不想将我的源代码分享给使用我的库项目的其他人，所以我创建了一个分布式库项目，其中我将上述主库项目的 jar 添加到分布式库项目的libs/文件夹中，并从主库项目到分布式库项目。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:custom="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <com.my.android.library.layout.CustomView
        custom:title_text = "THIS IS TITLE" 
        />
