    <p>I have an app that I'm trying to set up so that when I receive a text containing a certain phrase (Currently set to "This is a test" just to test it), a button onClick event will fire. If my message receiver was in my main activity, I could simply call .performClick(). However, I cant get it to work unless the message receiver is in a seperate class.</p> <p>MessageReceiver.java</p> <pre><code>package com.defsoftsol.snow.alert; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.telephony.SmsMessage; import android.util.Log; import android.widget.Toast; public class MessageReceiver extends BroadcastReceiver { public void onReceive(Context context, Intent intent) { Bundle pudsBundle = intent.getExtras(); Object[] pdus = (Object[]) pudsBundle.get("pdus"); SmsMessage messages =SmsMessage.createFromPdu((byte[]) pdus[0]); Log.i("MessageBody", messages.getMessageBody()); if(messages.getMessageBody().contains("This is a test")) { Toast.makeText(context, "It worked", Toast.LENGTH_LONG).show(); } } } </code></pre> <p>How can I do a performClick() on a button thats in MainActivity.java? Can I somehow access the View from that class?</p> <p>manifest entry</p> <pre><code>&lt;receiver android:name=".MainActivity.MessageReceiver" android:exported="true"&gt; &lt;intent-filter&gt; &lt;action android:name="android.provider.Telephony.SMS_RECEIVED"&gt;&lt;/action&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; </code></pre> <p>Logcat from crash when receive text with receiver in mainactivity.java</p> <pre><code>01-30 20:31:57.002: E/AndroidRuntime(32555): FATAL EXCEPTION: main 01-30 20:31:57.002: E/AndroidRuntime(32555): java.lang.RuntimeException: Unable to instantiate receiver com.defsoftsol.snow.alert.MainActivity.MessageReceiver: java.lang.ClassNotFoundException: com.defsoftsol.snow.alert.MainActivity.MessageReceiver 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.app.ActivityThread.handleReceiver(ActivityThread.java:2100) 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.app.ActivityThread.access$1500(ActivityThread.java:123) 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1197) 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.os.Handler.dispatchMessage(Handler.java:99) 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.os.Looper.loop(Looper.java:137) 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.app.ActivityThread.main(ActivityThread.java:4428) 01-30 20:31:57.002: E/AndroidRuntime(32555): at java.lang.reflect.Method.invokeNative(Native Method) 01-30 20:31:57.002: E/AndroidRuntime(32555): at java.lang.reflect.Method.invoke(Method.java:511) 01-30 20:31:57.002: E/AndroidRuntime(32555): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:787) 01-30 20:31:57.002: E/AndroidRuntime(32555): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:554) 01-30 20:31:57.002: E/AndroidRuntime(32555): at dalvik.system.NativeStart.main(Native Method) 01-30 20:31:57.002: E/AndroidRuntime(32555): Caused by: java.lang.ClassNotFoundException: com.defsoftsol.snow.alert.MainActivity.MessageReceiver 01-30 20:31:57.002: E/AndroidRuntime(32555): at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:61) 01-30 20:31:57.002: E/AndroidRuntime(32555): at java.lang.ClassLoader.loadClass(ClassLoader.java:501) 01-30 20:31:57.002: E/AndroidRuntime(32555): at java.lang.ClassLoader.loadClass(ClassLoader.java:461) 01-30 20:31:57.002: E/AndroidRuntime(32555): at android.app.ActivityThread.handleReceiver(ActivityThread.java:2095) 01-30 20:31:57.002: E/AndroidRuntime(32555): ... 10 more </code></pre>

Guidance
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).
