How to create specific log file in android?

· by · in
  • I am planning to automate the testing of an application by creating a log to store some results of execution of the app .

 

MainActivity.java

 

@ReportsCrashes(formKey=”google doc key”)
public class MainActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);

ACRA.init(this);
ACRA.getErrorReporter().setReportSender(new ErrorSender());

}

main_activity.xml

<?xml version=”1.0″ encoding=”utf-8″?>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”
xmlns:tools=”http://schemas.android.com/tools”
android:layout_width=”fill_parent”
android:layout_height=”match_parent”
android:orientation=”vertical” >

 

</LinearLayout>

 

 Download Jar file:

acra-4.5.0.jar

 

ErrorSender.class

public class ErrorSender implements ReportSender {

@Override
public void send(CrashReportData report) throws ReportSenderException {
String log = createCrashLog(report);

//Display Crash Report here
Log.w(“CrashReport”, log);

}

private String createCrashLog(CrashReportData report) {
Date now = new Date();
StringBuilder log = new StringBuilder();

log.append(“Package: “).append(report.get(ReportField.PACKAGE_NAME)).append(“\n”);
log.append(“Version: “).append(report.get(ReportField.APP_VERSION_CODE)).append(“\n”);
log.append(“Android: “).append(report.get(ReportField.ANDROID_VERSION)).append(“\n”);
log.append(“Manufacturer: “).append(android.os.Build.MANUFACTURER).append(“\n”);
log.append(“Model: “).append(report.get(ReportField.PHONE_MODEL)).append(“\n”);
log.append(“Date: “).append(now).append(“\n”);
log.append(“\n”);
log.append(“Report: “).append(report.get(ReportField.STACK_TRACE));

return log.toString();
}

}

 

Output:

 like this:

Package: your package name
Version: 1
Android: Device  Version
Manufacturer: Device company
Model: Device  name
Date: date & Time

Report: java.lang.NullPointerException
