Remember to backup your /sdcard/Android/data/com.mfreitas.twister/files/twisterwallet.dat! Since this is not the final location for the wallet file you may lose your private key with upcoming app updates. Hint: Copy-pasting your secret key to Android Memo is also quite handy.
Android porting of html UI is quite hacky. Not all features work. Prefer the Mobile version.
When opening twister simple web app, an error loading home url is shown. Wait a few seconds and try again (the daemon is still initializing).
Android browser seems to hide the upper-left of menu bar in Desktop version. You may try using a different browser instead, like Chrome. Or use Mobile version instead.
Android 2.x browser doesn’t support HTML5 FileReader so configuring avatar image is not possible. The workaround is to set your profile from PC.
When creating a new user, the Android browser may report that the AJAX request has timed out. This is not really a problem because the processing will still be performed by the daemon even if the browser aborts. Wait a few minutes and reload the interface, the user will probably have been created already.
Android simpleweb app’s CPU usage is not high, but memory usage of both the daemon and webview may render it pretty slugguish in low-end phones. The definitive twister android client needs to be native app (Java).
