取得聯絡電話號碼當機

Question

我試圖讓用戶選擇一個聯系人並檢索他的電話號碼。 我在https://developer.android.com中找到了以下代碼

//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
        }         
    }
}

我不知道為什么，但是當用戶選擇聯系人時，應用程序崩潰並顯示以下錯誤：E / EGL_emulation：tid 5883：eglSurfaceAttrib（1165）：錯誤0x3009（EGL_BAD_MATCH）。 從調試來看，它似乎在此行崩潰：

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

編輯：logcat消息：

03-07 11：16：53.239 5866-5883 / com.example.roy.wakeapp I / OpenGLRenderer：初始化的EGL版本1.4 03-07 11：16：53.265 5866-5883 / com.example.roy.wakeapp E / EGL_emulation ：tid 5883：eglSurfaceAttrib（1165）：錯誤0x3009（EGL_BAD_MATCH）03-07 11：16：53.265 5866-5883 / com.example.roy.wakeapp W / OpenGLRenderer：無法在表面0xad1ab480上設置EGL_SWAP_BEHAVIOR，錯誤= EGL_BAD_MAT

我試圖查找它，但找不到原因。 如果有人知道原因或可以提供其他方式，我會很高興的:)

謝謝！

嘗試如下實例化Intent

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

和活動結果法

@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();
        }
    }
