这是我在 Stack Overflow 上的第一个问题，如果我应该以不同的格式设置它，请告诉我。
我正在编写一个 Android 移动(电话)应用程序，它将与配套的 Android Wear( watch )应用程序进行交互。当我直接通过 adb 安装时，这两个应用程序都可以工作。我正在尝试创建一个 APK，它将通过电子邮件附件安装到手机上，并自动将配套应用推送到我的 watch 。但是，当我创建 APK 并通过电子邮件附件进行安装时，此 APK 并未成功将配套应用推送到我的 watch 。
当我通过 $ adb -d logcat | 读取安装日志时grep 1329，我得到以下结果(如下)。有人会碰巧知道我做错了什么吗？我试图在线查找错误消息，但没有找到任何有用的信息。

还有很多行 W/StreamManager( 1329): Dropping non-bitmap icon from notification. 在输出中间隔。为清楚起见，我已删除它们。
注意事项
- 我正在使用命令行 SDK 工具集，并已按照 Android developer's webpage 上的“手动打包”说明对应用程序进行签名和“签署您的申请”。
- 我目前正在使用 Android SDK 命令行工具包，但如果需要，我愿意使用 Android Studio。
- 硬件:我正在三星 Galaxy S5 和华硕 ZenWatch 2 上进行测试。
- 我将 wear apk 从“wear-release-unsigned.apk”重命名为“wear_release_unsigned.apk”，并将其放入移动应用程序的
/res/raw/目录中。与名字相反，它实际上是签名的。 - Original source code在 github 上可用。
非常感谢大家。
更新
我已经修改了手机和穿戴应用程序的版本。日志如下。和上次一样，这些都是 1329 的 grep。我还删除了“删除非位图”行。

最佳答案
好吧，我解决了我自己的问题。根据 Android 开发者网页，“阅读并理解签署您的应用程序很重要”。然后他们链接到我没有完全阅读的页面。
通过向我的 build.gradle 文件添加适当的配置而不是使用 jarsigner 手动签名，一切都安装得很好。
