【问题描述】：

我正在尝试让用户选择一个联系人并检索他的电话号码。我找到了以下代码here。

//the onClick function for the user to pick his contact

public void pickContact(View view) {
    Intent intent = new Intent(Intent.ACTION_PICK);
    intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(intent, REQUEST_SELECT_PHONE_NUMBER);
    }
}

//the function that should retrieve the phone number

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_SELECT_PHONE_NUMBER && resultCode == RESULT_OK) {
        // Get the URI and query the content provider for the phone number
        Uri contactUri = data.getData();
        ContentResolver resolver = getContentResolver();

        String[] projection = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER};
        Cursor cursor = resolver.query(contactUri, projection, null, null, null);
        // If the cursor returned is valid, get the phone number
        if (cursor != null && cursor.moveToFirst()) {
            int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            String number = cursor.getString(numberIndex);
            // Do something with the phone number
        }         
    }
}

我不知道为什么，但是当用户选择联系人时，应用程序崩溃并出现以下错误：E/EGL_emulation: tid 5883: eglSurfaceAttrib(1165): error 0x3009 (EGL_BAD_MATCH)。从调试来看，似乎在这一行崩溃了：

Cursor cursor = resolver.query(contactUri,
                projection, null, null, null);

logcat 消息：

我试图查找它，但我找不到原因。如果有人知道原因或可以提供不同的方法，我将不胜感激。

【问题讨论】：

你遇到了什么崩溃？？
您必须在此处粘贴完整的堆栈跟踪。
@Yashasvi 我如何获得完整的堆栈跟踪？
我得到 E/EGL_emulation: tid 5883: eglSurfaceAttrib(1165): error 0x3009 (EGL_BAD_MATCH)。
一旦发生崩溃，你会在 android studio logcat 中看到堆栈跟踪

【解决方案1】：

尝试如下实例化Intent

    Intent intent = new Intent(Intent.ACTION_PICK);
    intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
    startActivityForResult(intent, CONTACT_PICK);

及活动结果方法

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CONTACT_PICK && resultCode == RESULT_OK) {
            // Get the URI and query the content provider for the phone number
            Uri contactUri = data.getData();
            String[] projection = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER};
            Cursor cursor = getApplicationContext().getContentResolver().query(contactUri, projection,
                    null, null, null);

            // If the cursor returned is valid, get the phone number
            if (cursor != null && cursor.moveToFirst()) {

                int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

                String number = cursor.getString(numberIndex);

            }
            cursor.close();
        }
    }
