ACRA : How can I write ACRA report to file (in SD Card)?

I can use ACRA library to manage force close error by handling uncaught exception. The report can sent to google doc., email and custom web service successfully..

But what I want..

• How can I write the report to file [ex. sdcard/myapp/myLog.txt] ?

why I want this..

• My app user may not have internet connection while force close occurs.. if so then I will miss the report, if i write the report to file then I can sent to my server when the internet connection available.

I think what you want to achieve is already done by ACRA. Here's what I see in my abd logcat :

01-23 12:15:28.056: D/ACRA(614): Writing crash report file.
01-23 12:15:28.136: D/ACRA(614): Mark all pending reports as approved.

First thing that ACRA does is creating a report on a file on the inner storage of your app. Then if you're online and the errorreporter is correctly initialized, it sends the report. Otherwise, the reports are kept in the data storage (for a later sending).

I didn't look into the data but I'm currently working on a custom logger. So if you want to do the same things than ACRA, it's easy :

    ACRA.init(this);

    // a custom reporter for your very own purposes
    ErrorReporter.getInstance().setReportSender(new LocalReportSender(this));

And then :

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

import org.acra.ACRA;
import org.acra.CrashReportData;
import org.acra.ReportField;
import org.acra.sender.ReportSender;
import org.acra.sender.ReportSenderException;

import android.content.Context;

import de.akquinet.android.androlog.Log;

public class LocalReportSender implements ReportSender {

private final Map<ReportField, String> mMapping = new HashMap<ReportField, String>() ;
private FileOutputStream crashReport = null; 

public LocalReportSender(Context ctx) {
    // the destination
    try {
        crashReport = ctx.openFileOutput("crashReport", Context.MODE_WORLD_READABLE);
    } catch (FileNotFoundException e) {
        Log.e("TAG", "IO ERROR",e);
    }
}

@Override
public void send(CrashReportData report) throws ReportSenderException {

    final Map<String, String> finalReport = remap(report);

    try {
        OutputStreamWriter osw = new OutputStreamWriter(crashReport);

        Set set = finalReport.entrySet();
        Iterator i = set.iterator();

        while (i.hasNext()) {
            Map.Entry<String,String> me = (Map.Entry) i.next();
            osw.write("[" + me.getKey() + "]=" + me.getValue());
        }

        osw.flush();
        osw.close();
    } catch (IOException e) {
        Log.e("TAG", "IO ERROR",e);
    }

}

private static boolean isNull(String aString) {
    return aString == null || ACRA.NULL_VALUE.equals(aString);
}

private Map<String, String> remap(Map<ReportField, String> report) {

    ReportField[] fields = ACRA.getConfig().customReportContent();
    if (fields.length == 0) {
        fields = ACRA.DEFAULT_REPORT_FIELDS;
    }

    final Map<String, String> finalReport = new HashMap<String, String>(
            report.size());
    for (ReportField field : fields) {
        if (mMapping == null || mMapping.get(field) == null) {
            finalReport.put(field.toString(), report.get(field));
        } else {
            finalReport.put(mMapping.get(field), report.get(field));
        }
    }
    return finalReport;
}

}

I didn't fully tested it yet but you get the idea. Hope it helps.
