如何使用adb shell显示本地图像

Question

我想用adb shell它告诉我的设备在SD卡上显示图像.我以为这个命令会起作用:

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

不幸的是我收到此错误:

开始:Intent {act = android.intent.action.MAIN cmp = com.android.browser/.BrowserActivity}
错误类型3
错误:活动类{com.android.browser/com.android.browser.BrowserActivity}不存在.

我也试过做一个VIEW动作,只尝试使用-n或-d参数.

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

仅使用-d参数会导致此错误(我尝试使用和不使用路径上的"file://"前缀):

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

该文件的权限是:

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

我正在使用运行4.1.1的扎根Galaxy Nexus进行测试.

更新:我尝试了dtmilano的建议,但裁剪工具提供了"无法加载图像"弹出窗口.来自logcat的堆栈跟踪是:

我想知道这是否是内部SD卡,也许图像被视为应用程序数据,因此其他应用程序无法访问它？

Answer 1

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" 完成"操作中选择" 图库",则它不起作用,但如果选择" 裁剪图片",则无效.也适用于Astro Image Viewer.
