[HOWTO] Share screen and mirroring to chromecast on the Galaxy Tab 2

This is a quick tip to get chromecast screen share (or screen mirroring working). As you know, the latest official version from Samsung is the android 4.2.2, which doesn't have the screen mirroring feature. It has the ability to share specific apps via the chromecast app, however not all media apps appear there, games, etc. The errors that you may get if doesn't work properly are:

- Screen Casting is not optimized for this device; your experience may vary
- Casting screen to chromecast has ended

The rom that works is for the Galaxy Tab 2 P5100:

[ROM][P51xx][5.1.1] Samsung Galaxy Tab 2 AOSP-Project

Just click on the share icon on the notification toolbar and there you go. You don't even need the chromecast app except if you want to send specific apps (faster). If there's any issue and the screen goes black and stays black, or goes black and then quits, try changing the tablet DPI to 100 and try again. Then switch back to DPI 160 and should work:

- Connect via adb to the tablet

- To view current dpi:

Code:

---

adb shell dumpsys display | grep mBaseDisplayInfo

---

- To change to 100 dpi for example:

Code:

---

adb shell wm density 100 && adb reboot

---

After doing the dpi change from the first time the chromecast should notice and work from now on. Most or all 4.4.4+ roms should work.

Show site, image or file with Chromecast on TV

Hello there,

I want to use my Chromecast to view a Web site, an image or a file (e.g. HTML file) on a screen. Basically, to be informed about an Android app or website Chromecast that he opens it independently and then displays without further interaction.
According to the Google Developer Page developers.google.com/cast/docs/custom_receiver , this should be possible.


Actually this principle is already being used in media libraries or the Youtube app. Are there any specific examples or information about development?

Mfg,

Sissie
