Android 应用无法在 bluestack 中启动
Android app won't start in bluestack
我正在尝试学习本教程 http://www.androidhive.info/2015/04/android-getting-started-with-material-design/。当我到达第 13 步时我测试了该应用程序并且它工作正常但是当我到达第 23 步时 Navigation Drawer 我遇到了一个问题
android.support.v7.widget.RecyclerView cannot be instantiated
阅读其他网站关于此问题的评论后，我得出结论，我必须在预览面板上设置 API 级别 22，但由于我的 ADT 与它不兼容，我尝试更新它（我的 ADT ) 一切顺利，直到我到达第 23 步，我现在尝试测试我的应用程序是否 运行ning 基于教程。令我沮丧的是，ADT 是
unable to bind xxxx to DDMS
我尝试按照包括本网站在内的各个网站的其他说明再次修复错误。我从 windows 主机文件中添加了 127.0.0.1 localhost 因为有 none 除了它刚刚被评论。我什至尝试在 cmd 中使用此代码 adb kill-server 和 adb start-server。我还去了 window -> preference -> Android -> DDMS 并在那里尝试输入值 8601 on Base local debugger port 和 check the use ADBHOST 并添加了 values 127.0.0.1。我一一做了，但不幸的是错误仍然存在。
我面临的问题是应用无法启动或 运行 在 bluestack 上。我尝试了 运行ning 我的其他应用程序项目，看看它们是否恰好也没有 运行 但似乎它们 运行ning 顺利并且没有错误或在 bluestack 上崩溃所以我想通了与我在上述教程中关注的项目有关，但我不知道如何解决，因为我的所有代码都很好，没有红色标记或错误，但它们只是有警告，看起来没问题我.
这是我的 Manifest.xml（您可以在上面的教程中看到其余代码，直到第 23 步）
<?xml version="1.0" encoding="utf-8"?>

我的 SDK 已经是最新的，最新版本是 23，我的支持库也是 23。
这是我的 LogCat 我添加了从冗长到错误的所有内容：

您的问题是：
02-21 18:56:42.596: E/AndroidRuntime(15781): Caused by: android.view.InflateException: Binary XML file line #36: Error inflating class fragment
...二进制 XML 文件行 #36...
确保您的布局 xml 文件正确。
看看这个：
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.eureka4.studentdictionary.FragmentDrawer"
顺便说一下，我建议您使用 GenyMotion 而不是 BlueStacks。
截至 2020 年，使用 Android SDK 附带的 Android 模拟器可能是测试应用程序的最佳方式。
确保所有导入都是正确的并仔细检查依赖项。最好是删除它们并重新添加它们。重建您的项目并重试。
可能的解决方案：
- 重建
- 清理项目，确保所有依赖项都正确并再次测试应用程序
- 在另一个模拟器上测试
- 确保您的主题是正确的
- 确保您需要的所有文件都存在
经过无数小时试图解决问题。我以某种方式设法解决了这个问题，所以我要回答我自己的问题 post，希望它也能帮助其他人。考虑到我已经将 java 类 组织到不同的包中，即 com.eureka4.studentdictionary.adapter、com.eureka4.studentdictionary.model 和 com.eureka4.studentdictionary.activity，我一定忽略了我的 xml 文件上的包路径（感谢 @xdevs23 提供的术语）。对于解决方案，我尝试折射所有 java 文件并将它们移动到我的主包 com.eureka4.studentdictionary。问题似乎已经解决了。
或者：
@xdevs23 的回答也可能有帮助。
总结：
确保所有引用 java 类 的文件都添加了正确的包（但不确定在 Eclipse 中添加包是否会导致问题）。
我正在尝试学习本教程 http://www.androidhive.info/2015/04/android-getting-started-with-material-design/。当我到达第 13 步时我测试了该应用程序并且它工作正常但是当我到达第 23 步时 Navigation Drawer 我遇到了一个问题
android.support.v7.widget.RecyclerView cannot be instantiated
阅读其他网站关于此问题的评论后，我得出结论，我必须在预览面板上设置 API 级别 22，但由于我的 ADT 与它不兼容，我尝试更新它（我的 ADT ) 一切顺利，直到我到达第 23 步，我现在尝试测试我的应用程序是否 运行ning 基于教程。令我沮丧的是，ADT 是
unable to bind xxxx to DDMS
我尝试按照包括本网站在内的各个网站的其他说明再次修复错误。我从 windows 主机文件中添加了 127.0.0.1 localhost 因为有 none 除了它刚刚被评论。我什至尝试在 cmd 中使用此代码 adb kill-server 和 adb start-server。我还去了 window -> preference -> Android -> DDMS 并在那里尝试输入值 8601 on Base local debugger port 和 check the use ADBHOST 并添加了 values 127.0.0.1。我一一做了，但不幸的是错误仍然存在。
我面临的问题是应用无法启动或 运行 在 bluestack 上。我尝试了 运行ning 我的其他应用程序项目，看看它们是否恰好也没有 运行 但似乎它们 运行ning 顺利并且没有错误或在 bluestack 上崩溃所以我想通了与我在上述教程中关注的项目有关，但我不知道如何解决，因为我的所有代码都很好，没有红色标记或错误，但它们只是有警告，看起来没问题我.
这是我的 Manifest.xml（您可以在上面的教程中看到其余代码，直到第 23 步）

您的问题是：
02-21 18:56:42.596: E/AndroidRuntime(15781): Caused by: android.view.InflateException: Binary XML file line #36: Error inflating class fragment
...二进制 XML 文件行 #36...
确保您的布局 xml 文件正确。
看看这个：
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.eureka4.studentdictionary.FragmentDrawer"
顺便说一下，我建议您使用 GenyMotion 而不是 BlueStacks。
截至 2020 年，使用 Android SDK 附带的 Android 模拟器可能是测试应用程序的最佳方式。
确保所有导入都是正确的并仔细检查依赖项。最好是删除它们并重新添加它们。重建您的项目并重试。
可能的解决方案：
- 重建
- 清理项目，确保所有依赖项都正确并再次测试应用程序
- 在另一个模拟器上测试
- 确保您的主题是正确的
- 确保您需要的所有文件都存在
经过无数小时试图解决问题。我以某种方式设法解决了这个问题，所以我要回答我自己的问题 post，希望它也能帮助其他人。考虑到我已经将 java 类 组织到不同的包中，即 com.eureka4.studentdictionary.adapter、com.eureka4.studentdictionary.model 和 com.eureka4.studentdictionary.activity，我一定忽略了我的 xml 文件上的包路径（感谢 @xdevs23 提供的术语）。对于解决方案，我尝试折射所有 java 文件并将它们移动到我的主包 com.eureka4.studentdictionary。问题似乎已经解决了。
或者： @xdevs23 的回答也可能有帮助。
总结： 确保所有引用 java 类 的文件都添加了正确的包（但不确定在 Eclipse 中添加包是否会导致问题）。
