JarCastingHistorian
Historian is a custom Timber.Tree implementation that saves logs to SQLite, so that you can see/download the SQLite file later for debugging.
This library is primarily made to help debugging crash in consumers' devices.
Installation
Historian is distributed via Maven Central.
dependencies {
compile 'net.yslibrary.historian:historian-core:LATEST_LIBRARY_VERSION'

}
Usage
class App extends Application {
Historian historian;
@Override
public void onCreate() {
historian = Historian.builder(context)
// db name. defaults to "log.db"
.name("log.db")
// a directory where the db file will be saved. defaults to `context.getFiles()`.
// The directory will be created if it does not exist.
.directory(new File(Environment.getExternalStorageDirectory(), "somedir"))
// max number of logs stored in db. defaults to 500
.size(500)
// log level to save
.logLevel(Log.INFO)
.debug(true)
.build();
// initialize historian
historian.initialize();
Timber.plant(HistorianTree.with(historian));
// delete all saved logs
historian.delete();
// provide db path in Uri
historian.dbPath();
}
}
