Nasty problem: blank screen after resuming app, then app freezes (ANR keyDispatchingTimedOut)

You must Login before you can answer or comment on any questions.

Hope someone can help me out here. I am working on some apps that all have the same problem: blank (black in my case) screen after being to long in the background. App then freezes and the generated report says: 

ANR keyDispatchingTimedOut in TiTabActivity
Freeze
Activity appname.android.app/ti.modules.titanium.ui.TiTabActivity
Cause ANR keyDispatchingTimedOut
Also tried adapting my tiapp.xml, without any luck, looks like this: 
<android xmlns:android="http://schemas.android.com/apk/res/android">
        <tool-api-level>8</tool-api-level>
        <manifest android:installLocation="auto" android:versionCode="2" android:versionName="1.1">
            <uses-sdk android:minSdkVersion="7" />
            <supports-screens android:anyDensity="true"
                android:largeScreens="true" android:normalScreens="true" android:smallScreens="true"/>
            <application>
                <activity android:alwaysRetainTaskState="true"
                    android:configChanges="keyboardHidden|orientation"
                    android:label="Applabel"
                    android:name=".ApplabelActivity" android:theme="@style/Theme.Titanium">
                    <intent-filter>
                        <action android:name="android.intent.action.MAIN"/>
                        <category android:name="android.intent.category.LAUNCHER"/>
                    </intent-filter>
                </activity>
            </application>
        </manifest>
    </android>
Using Studio 1.0.7.201112281340, SDK 1.8.0.1, deploying on Android 4.0/4.0.3

Also tried latest builds/Android 2.2.3 and older builds (1.7.6). Problem's still there.

  • Hello,

    is this happening on simulator and device? If you can reproduce in Android 2.x, can you share a little bit of code that reproduces this issue? So we can help better.

    Best,

    Mauro

  • hello mauro,

    this is not happening in the emulator, only device (tested on multiple devices: galaxy s2, galaxy Y and a HTC).

    My app structure is like kitchensink, very basic. Using a tabgroup and behind the tabs some basic tables with data from a feed.

    This is my app.js: http://pastebin.com/rkZ5tMzB

Note: I just tried a complete new build with Android 2.X, but same problem. Same **** black screen followed by an ativity error. I am getting frustrated after working on this for weeks and this bug doesn't seem to get away.

hope you can help!
