    <p>Just started working with Android. I imported existing project into eclipse, it crashes immediately when I try to run it with the following error logs:</p> <pre><code>06-05 10:23:38.655: W/dalvikvm(1711): Unable to resolve superclass of Lresearch/diabetes/android/appcore/MobileUnitActivity; (39) 06-05 10:23:38.655: W/dalvikvm(1711): Link of class 'Lresearch/diabetes/android/appcore/MobileUnitActivity;' failed 06-05 10:23:38.655: D/AndroidRuntime(1711): Shutting down VM 06-05 10:23:38.655: W/dalvikvm(1711): threadid=1: thread exiting with uncaught exception (group=0x410ef300) 06-05 10:23:38.683: E/AndroidRuntime(1711): FATAL EXCEPTION: main 06-05 10:23:38.683: E/AndroidRuntime(1711): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{research.diabetes.android/research.diabetes.android.appcore.MobileUnitActivity}: java.lang.ClassNotFoundException: research.diabetes.android.appcore.MobileUnitActivity 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1983) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2084) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.ActivityThread.access$600(ActivityThread.java:130) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1195) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.os.Handler.dispatchMessage(Handler.java:99) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.os.Looper.loop(Looper.java:137) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.ActivityThread.main(ActivityThread.java:4745) 06-05 10:23:38.683: E/AndroidRuntime(1711): at java.lang.reflect.Method.invokeNative(Native Method) 06-05 10:23:38.683: E/AndroidRuntime(1711): at java.lang.reflect.Method.invoke(Method.java:511) 06-05 10:23:38.683: E/AndroidRuntime(1711): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 06-05 10:23:38.683: E/AndroidRuntime(1711): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 06-05 10:23:38.683: E/AndroidRuntime(1711): at dalvik.system.NativeStart.main(Native Method) 06-05 10:23:38.683: E/AndroidRuntime(1711): Caused by: java.lang.ClassNotFoundException: research.diabetes.android.appcore.MobileUnitActivity 06-05 10:23:38.683: E/AndroidRuntime(1711): at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:61) 06-05 10:23:38.683: E/AndroidRuntime(1711): at java.lang.ClassLoader.loadClass(ClassLoader.java:501) 06-05 10:23:38.683: E/AndroidRuntime(1711): at java.lang.ClassLoader.loadClass(ClassLoader.java:461) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.Instrumentation.newActivity(Instrumentation.java:1053) 06-05 10:23:38.683: E/AndroidRuntime(1711): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1974) 06-05 10:23:38.683: E/AndroidRuntime(1711): ... 11 more </code></pre> <p>I'm not quite sure what is wrong. There are two parts at play: AndroidCore and AndroidUnit_Mobile. The AndroidCore is the meat of the application, where the MobileUnitActivity is located. AndroidUnit_Mobile uses AndroidCore to operate. I have posted manifests for both parts below.</p> <p>Manifest for AndroidCore:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="research.diabetes.android" andrnCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="8" /&gt; &lt;application android:icon="@drawable/ic_launcher" android:label="@string/app_name" &gt; &lt;service android:enabled="true" android:name="research.diabetes.android.appcore.ConnectionService" /&gt;&lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>Manifest for AndroidUnit_Mobile:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="research.diabetes.android" android:versionCode="1" android:versionName="1.0"&gt; &lt;uses-sdk android:minSdkVersion="8" /&gt; &lt;uses-permission android:name="android.permission.INTERNET" /&gt; &lt;uses-permission android:name="android.permission.CALL_PHONE" /&gt; &lt;uses-permission android:name="android.permission.CALL_PHONE" /&gt; &lt;uses-permission android:name="android.permission.READ_PHONE_STATE" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /&gt; &lt;uses-permission android:name="android.permission.VIBRATE" /&gt; &lt;uses-permission android:name="android.permission.WAKE_LOCK" /&gt; &lt;uses-permission android:name="android.permission.DISABLE_KEYGUARD" /&gt; &lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt; &lt;activity android:name="research.diabetes.android.appcore.MobileUnitActivity" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" android:windowSoftInputMode="adjustResize" &gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name="research.diabetes.android.appcore.EmergencyHandler" android:label="EmergencyMode" android:screenOrientation="portrait"/&gt; &lt;activity android:name="research.diabetes.android.appcore.EmergencySplashScreen" android:label="EmergencySplashScreen" android:screenOrientation="portrait"/&gt; &lt;service android:enabled="true" android:name="research.diabetes.android.appcore.ConnectionService" /&gt; &lt;receiver android:enabled="false" android:name="research.diabetes.android.appcore.DeviceStartIntentReceiver"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.BOOT_COMPLETED" /&gt; &lt;category android:name="android.intent.category.HOME" /&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre>

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).
