The startactivity(intent) method causes an error. Why?

I want after a click on the OK button the MenuActivity to be shown. I have already searched on the Internet to find an answer and tried everything. I haave the activity declared in the AndroidManifest and I also tried to use Intent(this, MenuActivity.class) and also the one with the action inside but it doesn't work.

Unfortunately I can't show you my Logcat because it doesn't work on my computer. (I always have to export the APK to test the App).
P.S. I am working with Android Studio 1.0.1
...Please HELP ME !

To open a new activity you simply have to call it like this inside the onClick method.
Intent intent = new Intent(v.getContext(), MenuActivity.class);
startActivity(intent);
So your onClick method will look like this.
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), MenuActivity.class);
startActivity(intent);
}
Hope this helps.

Is because you say MainActivity.this, but you aren't in the MainActivity context.
You could make a reference of your current context in onCreate() and save it in a field:
private Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
context = this;
//rest of your code here
}
and use it as:
Intent intent = new Intent(context, MenuActivity.class);
//Something else
context.startActivity(intent);

Go to your manifest file, you will for your MainActivity manifest:
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
Just copy them and paste them for your MenuActivity.
I had the same same problem than you and it worked for me, but I don't know why.
Good luck!

first make sure your AndroidManifest.xml file contain declaration of all Activities in your app, like
<activity android:name=".MenuActivity"/>
then you create new intent and start it where you need to start the second Activity
Intent intent = new Intent(v.getContext(), MenuActivity.class);
startActivity(intent);

In my case, I changed the targeted sdk to 19 and also find that you didn't define the uses-sdk in the manifest...!
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />

Try changing the uses-permission syntax like this:
<uses-permission android:name="android.permission.SEND_SMS"/>

} else if (type.startsWith("image/")) {

}
}

In the intent to start your other app you have to mention its package name like:
intent.setClassName("com.farhan.appb",
"com.farhan.appb.MainActivity");

I have solved my Problem:
my MainActivity from ApplicationA:
package com.example.applicationa;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
Button sendstring;
EditText edit_text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// startService(new Intent(MainActivity.this, MyService.class));
edit_text = (EditText) findViewById(R.id.edit_text);
sendstring = (Button) findViewById(R.id.sendstring);
sendstring.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
startService(new Intent(MainActivity.this, MyService.class));
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override

i can't redirect to next registration page when i click on to SIGN IN button

basically am a java developer but now am developing an android app.In my app i can't redirect to the next page when i click on to SIGN IN button and here is my code
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
public class MainActivity extends ActionBarActivity implements View.OnClickListener {

setContentView(R.layout.login);
log = (Button) findViewById(R.id.login);
sign = (Button) findViewById(R.id.signup);
log.setOnClickListener(this);
sign.setOnClickListener(this);
}
#Override
public void onClick(View v) {

switch(v.getId()) {
case R.id.login:
break;
case R.id.signup:
Intent open = new Intent("com.example.eblood.Register");
startActivity(open);
break;
}
}
}
}
Here is my next page java code
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

Intent in = new Intent("com.example.eblood.MainActivity");
startActivity(in);
break;
}
}
}

and the error am getting is android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.example.eblood.Register }
And here is my home.java
package com.example.eblood;
import android.app.Activity;
import android.content.Intent;

public class home extends Activity {
protected void onCreate(Bundle savedInstanceState) {

} catch (InterruptedException e){
e.printStackTrace();
} finally {
Intent openMainActivity = new Intent("com.example.eblood.MAINACTIVITY");
startActivity(openMainActivity);
}
}
};
timer.start();}{
}
}

Try this..
If you use Intent open = new Intent("com.example.eblood.Register"); you will get ActivityNotFoundException change it as Intent open = new Intent(MainActivity.this,Register.class);
Change this
Intent open = new Intent("com.example.eblood.Register");
startActivity(open);
to
Intent open = new Intent(MainActivity.this,Register.class);
startActivity(open);
also
change this
Intent in = new Intent("com.example.eblood.MainActivity");
startActivity(in);
to
Intent in = new Intent(Register.this,MainActivity.class);
startActivity(in);
EDIT
Change this.
Intent openMainActivity = new Intent("com.example.eblood.MAINACTIVITY");
startActivity(openMainActivity);
to
Intent openMainActivity = new Intent(home.this,MainActivity.class);
startActivity(openMainActivity);

Search activity won't launch?

I have implemented a search system in my app, and the search bar appears, but when enter is pressed the search activity doesn't load.
As well as this, the text typed into the search box is black. The action bar is also black, so is there a way to make it white on API 14+?

I don't receive a force close - it just doesn't launch the search activity.
Also, what permission should I set for the final provider? The android system must be able to execute it,
