my app force closes I do not know why. All it should do is vibrating when it is in the foreground and stop if it is not but when I start it on my phone it force closes. I added lines about vibrator usage into the manifest by hand. Maybe this is the problem. I have to anything else with it to be valid for the app?
My manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Your packages are a mess.
You define com.example.kevinboonemidi as your package in the manifest, declare your Activity to be in com.example.haptic and actually put your Activity in com.example.haptic_sof.
Change android:name="com.example.haptic.MainActivity" to android:name="com.example.haptic_sof.MainActivity" and your app should run, though you may need to end up using one package entirely at least to start with.

I have external package class (my custom library), which I want to include in the project. It uses Activity, but shows error as you see.
If I place this command in main project class, it works well... What to do?
Here is the code:
package com.__MyDefaultLibrary;

}
// ========== MY CUSTOM LIBRARY =============//
//button find
public Button fvb(int id) {

Update Answer just passing context to class
public class MyClass {
private static Context mContext;
private static Activity mActivity;
public MyClass(Context c) {
mContext= c;
}
public MyClass(Activity act) {
mActivity= act;
}
public static void showToastMethod() {
// then passing context or activity to
Toast.makeText(mContext, "mymessage ", Toast.LENGTH_SHORT).show();
// or Toast.makeText(mActivity, "mymessage ", Toast.LENGTH_SHORT).show();
}
}
Finally I got it working with the help of topic: How to display a Toast message in from a class that doesn't extend Activity
Problem was in my code. There was no need to call andorid.app at all. I didnt pass Activity to my external file, from where I couldnt call anything..
I had to pass activity like this (from main project file):
public MyExternalClass myEx = new MyExternalClass(Activity);
and needed some modifications...
I'm still having problems with the Method AccountManager.addAccountExplicitly.
I want to create a App which is submitting a User PW combo to a website.
The app should save the login data and therefore i wanted to use AccountManager:
HttpAuth.java:
package com.geberit.eismi.httpauth;
import android.os.Bundle;
import android.accounts.Account;
import android.accounts.AccountManager;
import android.app.Activity;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.HttpAuthHandler;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.EditText;
import android.widget.Button;
public class HttpAuth extends Activity {
private EditText field_username;
private EditText field_password;
private Button btn_login;
private AccountManager accountM;
private Account eismi;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
accountM = AccountManager.get(this);
eismi = new Account("eismi", "com.geberit.sap.t81");
boolean test = accountM.addAccountExplicitly(eismi, "testpassword", null);
field_username = (EditText) findViewById(R.id.field_user);
field_password = (EditText) findViewById(R.id.field_password);
btn_login = (Button) findViewById(R.id.btn_login);
field_username.setText(accountM.getPassword(eismi));
HttpAuth Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</intent-filter>
</activity>
</application>
</manifest>
Everytime when executing the step
boolean test = accountM.addAccountExplicitly(eismi, "testpassword", null);
my app is stopping!!
some output of the console:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.geberit.eismi.httpauth/com.geberit.eismi.httpauth.HttpAuth}: java.lang.SecurityException: caller uid 10039 is different than the authenticator's uid
I hope you can help me
Thanks Michi

any one would help me please? best regards.
You may want to change the MODIFY permission into a READ permission as you're not modifying phone state, but trying to read it:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
I tried your code but the value of the signalDBM will not change. It will stay the same even if there is no internet connection at all. I am trying to do something similar and your code was of good help for me but now I face that problem. Does that program changes the values for you? Please let me know..

But when I Launch the app., It force closes.
Do you have any suggestions?
Thanks for your answers
You are writing this line private MediaView media=new MediaView(this);,before the Activity is initiated.So 'this' keyword is force closing your application
Please use like this
public class PlayerActivity extends Activity {
/** Called when the activity is first created. */
private MediaView media;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(media);
media=new MediaView(this);
}
}

I uploaded my Android project made in Eclipse. The idea is that i have a service, which computes the sum of two random numbers. But when i press the OK Button, i don't see the result in that edit box... why? What i'm doing wrong? Please help
Thanks!
EDIT: The code:
//service class
package service;
import java.util.Random;
import com.android.AplicatieSuma;
import android.widget.EditText;
import android.widget.TextView;
public class ServiciuSuma
{
public ServiciuSuma() { }
public int CalculateSum()
{
Random generator=new Random();
int n=generator.nextInt();
int m=generator.nextInt();
return n+m;
}
}
The Application class:
package com.android;
import android.app.*;
import service.*;
public class ApplicationSum extends Application {
public ServiciuSuma service = new ServiciuSuma();
}
and the main Activity class:
package com.android;
import com.android.R;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.PorterDuffColorFilter;
import android.graphics.drawable.Drawable;
import android.graphics.PorterDuff;
import android.os.Bundle;
import android.provider.Settings;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
public class Activitate extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
View btn_ok = findViewById(R.id.btn_ok);
btn_ok.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
CalculeazaSuma();
}
});
}
private void CalculeazaSuma()
{
AplicatieSuma appState = ((AplicatieSuma)this.getApplication());
EditText txt_amount = (EditText)findViewById(R.id.txt_amount);
txt_amount.setText(appState.service.CalculateSum());
//BindData();
}
}
So that edit text does not show the sum of the random generated numbers, by the service. What's wrong?
Thanks
EDIT:
the manifest xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android"
android:versionCode="1"
android:versionName="1.0.1">
<supports-screens
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true" />
<application android:name="ApplicationSum" android:icon="#drawable/icon" android:label="#string/app_name" android:debuggable="true">
<activity android:label="#string/app_name" android:name=".Activitate">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="7" />
</manifest>
This fix will work:
txt_amount.setText(String.valueOf(appState.service.CalculateSum()));
Without that you pass integer and android thinks it's an id of a resource to display. You should really use DDMS to identify such problems.
Have you specified in manifest that you want ApplicationSum to be used as application class?
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<application
android:name="com.android.ApplicationSum">
...
</application>
</manifest>
Does this work?
public String CalculateSum()
{
Random generator=new Random();
int n=generator.nextInt();
int m=generator.nextInt();
String sum = Integer.toString(n+m) ;
Log.v("CalculateSum", "N+M = " + sum);
return sum;
}
