<p>How do I start my app from my other app? (they will not be package together)</p>

<p>Manifest of the second app:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.helloandroid"
      android:versionCode="1"
      android:versionName="1.0"&gt;
    &lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt;
        &lt;activity android:name=".HelloAndroid"
                  android:label="@string/app_name"&gt;
            &lt;intent-filter&gt;
                &lt;action android:name="android.intent.action.MAIN" /&gt;
                &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
                &lt;category android:name="android.intent.category.HOME"/&gt;
                &lt;category android:name="android.intent.category.DEFAULT"/&gt;
            &lt;/intent-filter&gt;
        &lt;/activity&gt;

        &lt;activity android:name=".HelloAndroid"&gt;
            &lt;intent-filter&gt;
                &lt;action android:name="com.example.helloandroid.HelloAndroid" /&gt;
            &lt;/intent-filter&gt;
        &lt;/activity&gt;

    &lt;/application&gt;


&lt;/manifest&gt;

<pre><code>startActivity(new Intent("com.example.helloandroid.HelloAndroid"));
</code></pre>

<pre><code>07-16 15:11:01.455: ERROR/Desktop(610): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.example.helloandroid.HelloAndroid }
</code></pre>
