android - 如何使用adb shell显示本 map 片

Question

我想使用 adb shell 告诉我的设备在其 SD 卡上显示图像。我认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

不幸的是我得到了这个错误:

Starting: Intent { act=android.intent.action.MAIN cmp=com.android.browser/.BrowserActivity }
Error type 3
Error: Activity class {com.android.browser/com.android.browser.BrowserActivity} does not exist.

我还尝试执行 VIEW 操作，并尝试仅使用 -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(我尝试在路径上使用和不使用“file://”前缀):

Starting: Intent { act=android.intent.action.VIEW dat=/storage/sdcard0/Android/data//files/myfile.jpg }
Error: Activity not started, unable to resolve Intent { act=android.intent.action.VIEW dat=/storage/sdcard0/Android/data//files/myfile.jpg flg=0x10000000 }

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 Galaxy Nexus 进行测试。

更新:我尝试了 dtmilano 的建议，但裁剪工具弹出“无法加载图像”。来自 logcat 的堆栈跟踪是:

ActivityManager: START {dat=file:///storage/sdcard0/Android/data/<mypackage>/Pictures/myfile.jpg typ=image/*

我想知道这是不是内置 SD 卡，也许图像被视为应用程序数据，所以其他应用程序无法访问它？

Answer 1

这应该可行，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，如果您在Complete action using... 中选择Gallery 则不起作用，但如果您选择Crop picture 则起作用.也适用于 Astro Image Viewer。
