Run exoplayer from command line

This is currently tested with exoplayer version 2.5.4.
am output:

So we can pass in URI.
BUT we can pass one and only one URI, this is the limitation.
Haven't found the solution yet.
Basic on this log(custom log):

PlayerActivityTAG: C.WIDEVINE_UUID.toString() = edef8ba9-79d6-4ace-a3c8-27dcd51d21ed
PlayerActivityTAG: C.PLAYREADY_UUID.toString() = 9a04f079-9840-4286-ab92-e65be0885f95
PlayerActivityTAG: C.PLAYREADY_UUID.toString() = 9a04f079-9840-4286-ab92-e65be0885f95

We can run exoplayer with command:

am start -W -a com.google.android.exoplayer.demo.action.VIEW -c android.intent.category.DEFAULT \
-d "https://storage.googleapis.com/wvmedia/cenc/h264/tears/tears.mpd" \
-e drm_scheme_uuid "edef8ba9-79d6-4ace-a3c8-27dcd51d21ed" \
-e drm_license_url "https://proxy.uat.widevine.com/proxy?provider=widevine_test" \
-e extension "mpd" \
"com.google.android.exoplayer2.demo/com.google.android.exoplayer2.demo.PlayerActivity"

Or run mixed stream:

public static final String URI_LIST_EXTRA = "uri_list";
...
if (ACTION_VIEW.equals(action)) {
      uris = new Uri[]{intent.getData()};
      extensions = new String[]{intent.getStringExtra(EXTENSION_EXTRA)};
    } else if (ACTION_VIEW_LIST.equals(action)) {
      String[] uriStrings = intent.getStringArrayExtra(URI_LIST_EXTRA);
      uris = new Uri[uriStrings.length];
      for (int i = 0; i < uriStrings.length; i++) {
        uris[i] = Uri.parse(uriStrings[i]);
      }
      extensions = intent.getStringArrayExtra(EXTENSION_LIST_EXTRA);
      if (extensions == null) {
        extensions = new String[uriStrings.length];
}

am start -W -a com.google.android.exoplayer.demo.action.VIEW_LIST -c android.intent.category.DEFAULT \
