Question

我在这里看到类似的问题，但没有人可以帮助我。我正在使用eclipse。在我的项目中，我使用RoundedImageView-master作为库。这意味着，我在没有来源的日食“主”项目和包名称的“gen”文件夹：com.makeramen.roundedimageview 和i appcompat_v7-project一起使用lib android-support-v7-appcompat.jar。

我用我的布局而不是“... res-auto”这个：

 xmlns:app="http://schemas.android.com/apk/lib/com.makeramen.roundedimageview"

在我的主要活动中我导入了这个：

import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.design.widget.NavigationView;
import android.support.design.widget.NavigationView.OnNavigationItemSelectedListener;

在我的Buildpath中，部分库出现了我的“主要”项目。现在我想开始我的应用程序，但我从cat_log获得：

我的控制台对我说：

[myExampleApp] Android Launch!
[myExampleApp] adb is running normally.
[myExampleApp] Performing com.hdd.myExampleApp.MainActivity activity launch
[2myExampleApp] Uploading myExampleApp.apk onto device '192.168.56.101:5555'
[2myExampleApp] Installing myExampleApp.apk...
[myExampleApp] Success!
[myExampleApp] Project dependency found, installing: main

[myExampleApp] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.hdd.myExampleApp/.MainActivity }

我想，我必须在我的清单中加入这样的内容：

 <uses-library android:name="com.makeramen.roundedimageview"/>

此包名出现在main-project的gen-folder中。当我开始这个时，我从我的控制台开始：

[myExampleApp] Android Launch!
[myExampleApp] adb is running normally.
[myExampleApp] Performing com.hda.myExampleApp.MainActivity activity launch
[myExampleApp] Uploading myExampleApp.apk onto device '192.168.56.101:5555'
[myExampleApp] Installing myExampleApp.apk...
[myExampleApp] Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY
[myExampleApp] Please check logcat output for more details.
[myExampleApp] Launch canceled!

我再也没有想法了，我能做些什么。请帮帮我:)。

您必须只使用xmlns:app="http://schemas.android.com/apk/res-auto"和 android自己找到了相对资源。
