I would like to send an array in different application.
So In the first application I have MainActivity. The Activity will start an intent. When I'm trying to make an intent, I found a problem. The problem is ShowArrayActivity "cannot be resolved to a type". Actually ShowArrayActivity class is in another apppication. I have tried to add project in build path, but I have an error message said that a cycle was detected in the build path of project 'sendIntent'..
package com.example.sendintent;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import com.example.sendintent.DisplayMessageActivity;
public class MainActivity extends Activity {
public static final String ARRAYS_COUNT = "com.example.sendintent.MainActivity.ARRAYS_COUNT";
public static final String ARRAY_INDEX = "com.example.sendintent.MainActivity.ARRAY_INDEX";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@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;
}
public void sendMessage(View view)
{
final String data[][] = new String[][]
{{"Car","75","loaded"},
{"Motor","25","loaded"},
{"Truck","30","loaded"},
{"Bike","40","loaded"},
{"Boat","10","loaded"}};
Bundle bundle = new Bundle();
int count = data.length;
bundle.putInt(ARRAYS_COUNT, count);
for (int i = 0; i < count; i++)
bundle.putStringArray(ARRAY_INDEX + i, data[i]);
Intent intent = new Intent(this, ShowArrayActivity.class); ---->ERROR
intent.putExtras(bundle);
startActivity(intent);
}
}
In Manifest I have declare
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sendintent"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.sendintent.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.sendintent.DisplayMessageActivity"
android:parentActivityName="com.example.sendintent.MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.sendintent.MainActivity" />
</activity>
<service android:name="com.example.sendintent.MainActivity" />
<receiver android:name="com.example.receiver.MainActivityReceiver">
<intent-filter>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_COUNT"/>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_INDEX"/>
</intent-filter>
</receiver>
</application>
</manifest>
In another application, I have declare the receiver for the intent. It called MainActivityReceiver
package com.example.receiver;
import java.util.ArrayList;
import com.example.sendintent.MainActivity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MainActivityReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
intent.setClass(context, MainActivity.class);
context.startService(intent);
}
}
I have another class called ShowArrayAcivity:
package com.example.receiver;
import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class ShowArrayActivity extends Activity {
public String[][] data;
public static final String ARRAYS_COUNT = "com.example.sendintent.MainActivity.ARRAYS_COUNT";
public static final String ARRAY_INDEX = "com.example.sendintent.MainActivity.ARRAY_INDEX";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
int count = bundle.getInt(ShowArrayActivity.ARRAYS_COUNT, 0);
ArrayList<String[]> arrays = new ArrayList<String[]>(count);
for (int i = 0; i < count; i++)
arrays.add(bundle.getStringArray(ShowArrayActivity.ARRAY_INDEX + i));
data = arrays.toArray(new String[][]{});
}
}
@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;
}
}
In Manifest for receiver application
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.receiver"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.receiver.ShowArrayActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="com.example.sendintent.MainActivity" />
<receiver android:name="com.example.receiver.MainActivityReceiver">
<intent-filter>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_COUNT"/>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_INDEX"/>
</intent-filter>
</receiver>
</application>
</manifest>
In receiver application, It won't show the array from sendIntent application in Interface. I just want to know the way to use broadcast and intent. So if I run in debug mode,in ShowArrayActivity, the variable data will containt the result of the intent.
So my questions is,why I can't use another class when I try to send the intent? Did I forgot something to implement for madethe communication between 2 application?
