Android available mime-types?

Solution 1:

I did some search these days.

maybe you shoud read these links.

• MediaStore supported MIME type is here: http://androidxref.com/4.4.4_r1/xref/frameworks/base/media/java/android/media/MediaFile.java#174
• And there is also a API URLConnection.getFileNameMap()
  • And its inner side is here: http://androidxref.com/4.4.4_r1/xref/libcore/luni/src/main/java/libcore/net/MimeUtils.java

Solution 2:

I couldn't find a place that could tell me every existent mime type for different types of media in android applications

There are over a million applications on the Play Store, plus others elsewhere (e.g., pre-installed on devices, Amazon AppStore for Android). A given device will have some combination of these apps. A given user will have access to some subset of the apps on the device, if the user is running in an Android 4.3+ restricted profile on a tablet.

Hence, there is no way to know, at compile time, what MIME types a given Android device can support for things like ACTION_VIEW activity requests. The OS itself supports no such MIME types -- they are all provided by applications.

Here are the ones I know that exist and work:

Some devices may have apps pre-installed that support those MIME types. text/plain is the least likely of your set to be supported "out of the box".
