我正在创建一个调用应用程序.

这是在Android 4.0和5.0上运行的自动答案; 而当我有一个来电应答呼叫按钮工作,但它不适用于Android 6.0.

我测试了这篇文章的答案,但它也不起作用:在Android 6.0中回答来电

IncomingActivity:

@Override
public void onClick(View v) {
    switch (v.getId())
    {
        case R.id.imgaccept:
        {
            if (Build.VERSION.SDK_INT >= 21) {
                new Thread(new Runnable() {

                    @Override
                    public void run() {

                        try {
                            Runtime.getRuntime().exec( "input keyevent " + KeyEvent.KEYCODE_HEADSETHOOK );
                            Intent intent = new Intent(getApplicationContext(), OutGoing.class);
                            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
                            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            intent.putExtra(CommonMethods.OUTGOING_NUMBER, savedNumber);
                            startActivity(intent);
                            finish();
                        }
                        catch (Throwable t) {

                        }
                    }
                }).start();
            }
            else {
                Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
                buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK)); …

我试图删除位于路径的文件

/storage/714D-160A/Xender/image/Screenshot_commando.png

到目前为止我做了什么:

  try{
        String d_path = "/storage/714D-160A/Xender/image/Screenshot_commando.png";
        File file = new File(d_path);
        file.delete();

     }catch(Exception e){

        e.printStackTrace();
     }

并且文件仍在其位置(未删除:()

我也在Manifest文件中获得了许可.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.STORAGE" />

我创建一个应用程序来读取、更新、删除联系人详细信息。这是更新联系人姓名和电话号码的问题。有人可以帮助我吗？我该怎么做。我正在使用以下代码，但它不起作用。

  @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    final View view = inflater.inflate(R.layout.fragment_fragment_edit, container, false);

    textView = (TextView) view.findViewById(R.id.tvnew1);

    imageView = (ImageView) view.findViewById(R.id.newim1);
    save = (Button) view.findViewById(R.id.savebtn1);

    fName = (EditText) view.findViewById(R.id.firstname1);
    lName = (EditText) view.findViewById(R.id.lastname1);
    pNumber = (EditText) view.findViewById(R.id.pnumber1);

    String conName = getArguments().getString("name");
    String conNumber = getArguments().getString("number");
    int conId = getArguments().getInt("pos");

    Log.e("a", "name is : " + conName);
    Log.e("a", "number is : " + conNumber);
    Log.e("a", "id is :" + conId);

    fName.setText(conName);
    pNumber.setText(conNumber);

    imageView.setOnClickListener(new View.OnClickListener() {
        @Override …
