Non Solved Android Studios issue, Unfortunately
<p>I found out, that when I create a layout, and Java file, I'm making a codes, so when I press button, it takes me to the another activity. </p>

<p>I have called already 9 methods to send me to the other activity, 3 or 4 in a MainJava class, and 4 in a layout, and everything works fine. </p>

<p>But now 1 button, in the new layout, doesn't work and says "Unfortunately app has stopped". I can't figure out where is the real problem, but the code is like the other buttons, which work well. </p>

<p>I make the onClick button:</p>

<pre><code> &lt;RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center_horizontal"&gt;

    &lt;View
        android:layout_width="match_parent"

        android:background="@android:color/background_dark"
        android:id="@+id/line1"
        android:layout_below="@+id/textView45"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" /&gt;

    &lt;TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Level 3"
        android:id="@+id/textView45"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="23dp" /&gt;

    &lt;ImageButton
        android:layout_width="120dp"
        android:layout_height="120dp"
        android:id="@+id/imageButton2"
        android:layout_marginTop="34dp"
        android:onClick="sendPhone"
        android:background="@drawable/phone"
        android:layout_below="@+id/line1"
        android:layout_toLeftOf="@+id/textView45"
        android:layout_toStartOf="@+id/textView45" /&gt;

&lt;/RelativeLayout&gt;
</code></pre>

<p>Of course i make a command in the Java File:</p>

<pre><code> public void sendPhone(View view) {
    Intent intent = new Intent(getApplicationContext(), phoneclass.class);
    startActivity(intent);
}
</code></pre>

<p>And i create manifest file:</p>

<pre><code>activity android:name=".phoneclass"&gt;
</code></pre>

<p>As i said before, other 9 buttons works well, but one button is getting: "Unfortunately, app has stoped working". </p>
