android - 使用 multidex 和 google play 服务时应用程序崩溃

Question

这是我的第一个应用程序。我尝试添加 Admob，它需要 google play 服务和 Multidex 支持，所以我也添加了这些项目。

我的应用程序在 Android 5.1 中运行良好，但在 Android 3.2 中崩溃

我理解这个错误，因为它试图加载一些类，但在谷歌播放服务中找不到它们(我认为所以不确切知道)。

    android minSdkVersion="13"
    android targetSdkVersion="21"

我该如何解决？

Answer 1

要添加 Google Play 服务库，您不应将 jar 文件复制到您的项目中；您应该将 google play services 库项目导入到您的项目中。怎么办？

1. 将整个 Google Play 服务复制到您的工作区。 (google play服务库项目路径为:

   /extras/google/google_play_services/libproject/google-play-services_lib

2. 将 Google Play 服务库导入到您的项目中。右键单击您的 Android 项目。转到属性。在左侧面板中选择 Android。单击“添加”并浏览库项目。选择相同。单击“确定”并应用

向您的项目添加一些 jar:

1. 将 jar 文件复制到 libs 文件夹
2. 右键单击您的 Android 项目。转到属性。选择左侧面板上的 Java 构建路径。在“库”选项卡上，按“添加 jars...”按钮并浏览添加的 jar 文件，然后应用并确定。

向您的项目添加 multidex 支持:

请添加最新的支持库v4。

自动添加支持库 v4:

在 Eclipse 中:右键单击您的 Android 项目 -> Android 工具 -> 添加支持库。
