如何使用adb shell显示本地映像

Question

我想使用ADB shell告诉我的设备在其SD卡上显示图像。我以为这个命令会奏效：

adb shell am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity -d file:///storage/sdcard0/Android/data/<mypackage>/files/myfile.jpg

adb shell am start -a android.intent.action.VIEW -d file:///storage/sdcard0/Android/data/<mypackage>/files/myfile.jpg

开始：意图{act=Android.Intent.action.view dat=/storage/sdcard0/android/data//files/myfile.jpg}
错误：活动未启动，无法解析意图{act=Android.Intent.action.view dat=/storage/sdcard0/android/data//files/myfile.jpg flg=0x10000000}

该文件的权限为：

-rw-rw-r-- root     sdcard_rw   198106 2013-01-02 21:29 gUD9w5.jpg

我正在用Galaxy Nexus的4.1.1版本进行测试。

ActivityManager: START {dat=file:///storage/sdcard0/Android/data/<mypackage>/Pictures/myfile.jpg typ=image/* 
    flg=0x13000000 cmp=com.google.android.gallery3d/com.android.gallery3d.app.CropImage u=0} from pid 301

这应该有效，但它取决于您安装的应用程序：

$ adb shell am start -t image/* -d file:///mnt/sdcard/myfile.jpg

有趣的是，如果您使用...在完全操作中选择Gallery，它就不起作用，但如果您选择裁剪图片，它就起作用了。也与Astro图像查看器一起工作。
