FileUtils Api

http://commons.apache.org/proper/commons-io/javadocs/api-release/index.html?overview-summary.html

1 第三方jar导入

    implementation 'commons-io:commons-io:2.6'

2 使用(对于我来说主要操作 IOUtils,FileUtils)

import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import org.apache.commons.io.FileUtils;
import org.apache.commons.io.IOUtils;

import java.io.File;
import java.io.IOException;
import java.nio.charset.Charset;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String msg = "123";
        String path = Environment.getExternalStorageDirectory() + File.separator + "aaa" + File.separator + "aaaa.txt";
        File file = new File(path);
        try {
            IOUtils.toInputStream(msg,Charset.defaultCharset());
            FileUtils.writeStringToFile(file, msg, Charset.defaultCharset());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
