Hello Friends,
Today, I am sharing another android tutorial which helps you in Creating
and Storing Log File in your android phone.
1. MainActivity.java
package com.example.logfileimplementation;
import java.io.File;
import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
public static final String SDCARD = String.valueOf(Environment
.getExternalStorageDirectory());
TextView mTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
deleteLog();
setContentView(R.layout.activity_main);
createAppDirectories();
mTextView = (TextView) findViewById(R.id.action_settings);
mTextView.setText("Android crash Reporter");
} catch(Exception ex) {
Utilities.writeIntoLog(Log.getStackTraceString(ex));
}
}
@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;
}
// Creating App Directory For Log File
private void createAppDirectories() {
System.out.println("hiii");
File dir1 = new File(Utilities.APP_DIR);
if (!dir1.exists()) {
dir1.mkdir();
}
}
// Deleting App Directory which is used for Log File
private void deleteLog() {
File log = new File(Utilities.LOG_FILE_PATH);
if (log.exists()) {
log.delete();
}
}
}
2. Utilities.javapackage com.example.logfileimplementation;
import java.io.BufferedWriter;
import java.io.FileWriter;
public class Utilities {
public static String APP_DIR = MainActivity.SDCARD+"/Logfile";
public static String LOG_FILE_PATH = APP_DIR+"/ myapp_log.txt";
public static void writeIntoLog(String data)
{
FileWriter fw = null;
try {
fw = new FileWriter(LOG_FILE_PATH , true);
BufferedWriter buffer = new BufferedWriter(fw);
buffer.append(data+"\n");
buffer.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
3. activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> </RelativeLayout>4. AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.logfileimplementation"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.logfileimplementation.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>
</application>
</manifest>
Hope this will help you.Enjoy Coding. Cheers.... :)
