    <p>My app is working well on other phones without errors.</p> <p>I recently tested my app on an actual Samsung S4 and all of my canvas drawings are messed up. Some times they draw and sometimes they don't, it seems completely random. No errors are thrown regarding the canvas draw commands. I am not using any transitions.</p> <p>After reading many posts I disabled hardware acceleration by using</p> <pre><code>super.appView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); </code></pre> <p>And I also used the following to ensure the viewport wouldn't be skewed due to the higher resolution</p> <pre><code>&lt;meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, target-densitydpi=medium-dpi, user-scalable=0" /&gt; </code></pre> <p>Now when I run the app I do see some strange errors that are not seen when testing on other phones. I searched the net but didn't learn too much about them.</p> <pre><code>E/SELinux(23616): selinux_android_seapp_context_reload: seapp_contexts file is loaded from /seapp_contexts E/ViewRootImpl(23616): sendUserActionEvent() mView == null E/SpannableStringBuilder(23616): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length E/SpannableStringBuilder(23616): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length </code></pre> <p>I have no idea what these errors mean. sendUserActionEvent? I am not sending any action events. SPAN_EXCLUSIVE_EXCLUSIVE? I do not have any spans...</p> <p>Are there any other tips on getting Phonegap to run well on the S4???</p> <p>Here is my full log</p> <pre><code>10-29 19:11:22.189: E/SELinux(23616): selinux_android_seapp_context_reload: seapp_contexts file is loaded from /seapp_contexts 10-29 19:11:22.189: D/dalvikvm(23616): Late-enabling CheckJNI 10-29 19:11:22.279: D/CordovaActivity(23616): Setting integer properties in CordovaActivity will be deprecated in 3.0 on July 2013, please use config.xml 10-29 19:11:22.289: I/CordovaLog(23616): Changing log level to DEBUG(3) 10-29 19:11:22.289: D/CordovaActivity(23616): CordovaActivity.onCreate() 10-29 19:11:22.289: D/CordovaActivity(23616): Setting integer properties in CordovaActivity will be deprecated in 3.0 on July 2013, please use config.xml 10-29 19:11:22.349: I/webclipboard(23616): clipservice: android.sec.clipboard.ClipboardExManager@422752e8 10-29 19:11:22.379: D/CordovaWebView(23616): CordovaWebView is running on device made by: samsung 10-29 19:11:22.389: D/JsMessageQueue(23616): Set native-&gt;JS mode to 2 10-29 19:11:22.389: D/CordovaActivity(23616): CordovaActivity.init() 10-29 19:11:22.409: V/webkit(23616): BrowserFrame constructor: this=Handler (android.webkit.BrowserFrame) {4226f018} 10-29 19:11:22.459: D/dalvikvm(23616): GC_FOR_ALLOC freed 325K, 8% free 18099K/19532K, paused 25ms, total 25ms 10-29 19:11:22.459: I/dalvikvm-heap(23616): Grow heap (frag case) to 21.387MB for 2764816-byte allocation 10-29 19:11:22.479: D/dalvikvm(23616): GC_FOR_ALLOC freed 3K, 7% free 20796K/22236K, paused 13ms, total 13ms 10-29 19:11:22.489: D/dalvikvm(23616): GC_CONCURRENT freed 1K, 7% free 20807K/22236K, paused 3ms+2ms, total 17ms 10-29 19:11:22.499: D/CordovaWebView(23616): loadUrlIntoView(file:///android_asset/www/splash.html, 10000) 10-29 19:11:22.499: D/CordovaActivity(23616): onMessage(splashscreen,show) 10-29 19:11:22.499: D/CordovaWebView(23616): &gt;&gt;&gt; loadUrl(file:///android_asset/www/splash.html) 10-29 19:11:22.499: D/PluginManager(23616): init() 10-29 19:11:22.509: D/CordovaWebView(23616): &gt;&gt;&gt; loadUrlNow() 10-29 19:11:22.509: D/WebView(23616): loadUrlImpl: called 10-29 19:11:22.509: D/webcore(23616): CORE loadUrl: called 10-29 19:11:22.509: D/webkit(23616): Firewall not null 10-29 19:11:22.509: D/webkit(23616): euler: isUrlBlocked = false 10-29 19:11:22.509: I/CordovaLog(23616): Found start page location: splash.html 10-29 19:11:22.509: I/CordovaLog(23616): Changing log level to DEBUG(3) 10-29 19:11:22.509: D/CordovaActivity(23616): Resuming the App 10-29 19:11:22.509: D/CordovaActivity(23616): CB-3064: The errorUrl is null 10-29 19:11:22.549: D/libEGL(23616): loaded /system/lib/egl/libEGL_adreno200.so 10-29 19:11:22.549: D/libEGL(23616): loaded /system/lib/egl/libGLESv1_CM_adreno200.so 10-29 19:11:22.549: D/libEGL(23616): loaded /system/lib/egl/libGLESv2_adreno200.so 10-29 19:11:22.549: I/Adreno200-EGL(23616): &lt;qeglDrvAPI_eglInitialize:265&gt;: EGL 1.4 QUALCOMM build: (CL3579225) 10-29 19:11:22.549: I/Adreno200-EGL(23616): Build Date: 04/22/13 Mon 10-29 19:11:22.549: I/Adreno200-EGL(23616): Local Branch: adreno_sba_20130419 10-29 19:11:22.549: I/Adreno200-EGL(23616): Remote Branch: 10-29 19:11:22.549: I/Adreno200-EGL(23616): Local Patches: 10-29 19:11:22.549: I/Adreno200-EGL(23616): Reconstruct Branch: 10-29 19:11:22.619: D/OpenGLRenderer(23616): Enabling debug mode 0 10-29 19:11:22.619: D/SoftKeyboardDetect(23616): Ignore this event 10-29 19:11:22.629: D/WebView(23616): onSizeChanged - w:1080 h:1920 10-29 19:11:22.629: D/CordovaActivity(23616): onMessage(onPageStarted,file:///android_asset/www/splash.html) 10-29 19:11:22.760: D/SoftKeyboardDetect(23616): Ignore this event 10-29 19:11:22.770: D/SoftKeyboardDetect(23616): Ignore this event 10-29 19:11:23.400: I/Web Console(23616): BUILD TITLE: height: 480 width: 1080:135 10-29 19:11:23.410: D/skia(23616): new locale 10-29 19:11:23.420: I/GATE(23616): &lt;GATE-M&gt;DEV_ACTION_COMPLETED&lt;/GATE-M&gt; 10-29 19:11:23.420: D/CordovaWebViewClient(23616): onPageFinished(file:///android_asset/www/splash.html) 10-29 19:11:23.420: D/CordovaActivity(23616): onMessage(onPageFinished,file:///android_asset/www/splash.html) 10-29 19:11:23.470: D/CordovaActivity(23616): onMessage(spinner,stop) 10-29 19:11:23.470: D/CordovaNetworkManager(23616): Connection Type: wifi 10-29 19:11:23.480: D/TilesManager(23616): Starting TG #0, 0x6d237b38 10-29 19:11:23.480: D/TilesManager(23616): new EGLContext from framework: 40fc0920 10-29 19:11:23.480: D/GLWebViewState(23616): Reinit shader 10-29 19:11:23.490: D/CordovaActivity(23616): onMessage(splashscreen,hide) 10-29 19:11:23.490: I/App(23616): WARNING: Back Button Default Behaviour will be overridden.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
