Hey Guys, Today I am going to share the important code of Assets. How to open the file and read the file from assets folder. In that Scenario, There is a class in Android API AssetManager.
Open file with AssetManager
package app.test;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.StringTokenizer;
import android.app.Activity;
import android.content.res.AssetManager;
import android.os.Bundle;
import android.widget.TextView;
public class Test extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
setContentView(tv);
try {
AssetManager manager = getAssets();
InputStream mInput = manager.open("data.csv");
byte[] data = new byte[128];
mInput.read(data);
mInput.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Read Asset Files
Cheers! Guys
package app.test;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import android.app.Activity;
import android.content.res.AssetManager;
import android.os.Bundle;
import android.widget.TextView;
public class Test extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
setContentView(textView);
AssetManager assetManager = getAssets();
InputStream inputStream = null;
try {
inputStream = assetManager.open("/text.txt");
String text = loadTextFile(inputStream);
textView.setText(text);
} catch (IOException e) {
textView.setText("Couldn't load file");
} finally {
if (inputStream != null)
try {
inputStream.close();
} catch (IOException e) {
textView.setText("Couldn't close file");
}
}
}
public String loadTextFile(InputStream inputStream) throws IOException {
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
byte[] bytes = new byte[4096];
int len = 0;
while ((len = inputStream.read(bytes)) > 0)
byteStream.write(bytes, 0, len);
return new String(byteStream.toByteArray(), "UTF8");
}
}
