How to access the phone's screen like "Chromecast APP"?(Mirroring)

I want make mirroring without WiFi-direct.

  • like chromecast mirroring function.
  • Chromecast application can access screen without rooting&wifi-direct.

I found "capture_video_output" permission at API 19, but I can`t found any API. So, I decompiled chromecast, but it hasn't "capture_video_output" permission.

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

Is it right way for mirroring?(wifi-display)

How can I make mirroring application? Or where can I get this info?

Solution

  • You can use Presentation APIs to mirror a view within your app (can be a virtual view) to a chromecast device if mirroring is happening. Otherwise, there is no API for you to mirror phone's screen to a chromecast device.
