无法通过Android的AccessibilityService访问通知 [英] Cannot access notification through Android AccessibilityService
本文介绍了无法通过Android的AccessibilityService访问通知的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图用AccessibilityService访问我的Android手机上的通知。
I am trying to access the notifications on my android phone using the AccessibilityService.
我试图使一个服务，然后从主要活动调用它。我还添加了荟萃的服务。它不工作。我看不到该服务的触发。
I tried making a service and calling it from the main activity. I've also added meta for the service. It's not working. I cannot see the triggering of the service.
我使用的是Android L系统进行测试。在辅助功能设置我已经添加了我的应用程序'通知'作为。
I'm using Android L for testing. In accessibility settings I've added my app 'Notify' as on.
在此先感谢。
我的主要活动
package com.example.tony.notify;
import android.content.Intent;
import android.provider.Settings;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// startActivityForResult(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS), 0);
Intent i = new Intent(this, MyAccessibilityService.class);
startService(i);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是我的服务类

}
private String getEventText(AccessibilityEvent event) {
StringBuilder sb = new StringBuilder();
for (CharSequence s : event.getText()) {
sb.append(s);
}
return sb.toString();
}
@Override

Log.v(TAG, String.format(
"onAccessibilityEvent: [type] %s [class] %s [package] %s [time] %s [text] %s",
getEventType(event), event.getClassName(), event.getPackageName(),
event.getEventTime(), getEventText(event)));
}
@Override
public void onInterrupt() {
Log.v(TAG, "onInterrupt");
}
@Override
protected void onServiceConnected() {
Toast.makeText(getApplicationContext(),"connected",Toast.LENGTH_SHORT).show();
super.onServiceConnected();
Log.v(TAG, "onServiceConnected");
AccessibilityServiceInfo info = new AccessibilityServiceInfo();
info.flags = AccessibilityServiceInfo.DEFAULT;
info.eventTypes = AccessibilityEvent.TYPES_ALL_MASK;
info.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
setServiceInfo(info);
}
}

我得到它的工作对L-虽然，它的真正的工作不是在API 16日，我在一个测试。任何人都可以提出一个除了让它在API工作14 +
I got it working on L though, it's not really working on api 16, I tested on one. Can anyone suggest an addition to make it work on api 14+
