Notes: For your safety, TeXPortal Free exits itself whenever it is interrupted (i.e. put to the background) such as when the screen rotates, you press the "Recent apps" button, switch to another app, etc. Therefore, please keep your screen on, lock screen rotation, do not plug in keyboard, etc. when compiling documents.
This app might download additional packages from the web. To save your data plan as well as for the best experience, run the app when you have a stable WIFI connection.
* Support EXTERNAL SD card in Android 5.0 Lollipop: use menu command "Grant SDcard access" on the action panel, pick the external SD card folder to grant the app access to it. Note that this is only applicable on Android 5.0 Lollipop; 4.4.x Kitkat users have no choice but only compile files on INTERNAL sdcard.
