搜索联系人上的java.lang.SecurityException
搜索联系人上的java.lang.SecurityException
提问于 2017-10-19 07:47:23
我在Google Play中的崩溃报告中有一个错误，我正在联系人列表中搜索联系人，以便知道我是否必须创建它，或者它是否已经存在，但它给我提供了Android 7.0设备上的java.lang.SecurityException。
这是我的代码：
public boolean contactExists() {
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(RegisterActivity.this,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(RegisterActivity.this,
Manifest.permission.READ_CONTACTS)) {
showMessageOKCancel("Necesitas permisos para guardar nuestro contácto en tu teléfono y poder enviarnos mensajes");
return false;
// Show an explanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
if (Bellisima_number != null) {
Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(Bellisima_number));
String[] mPhoneNumberProjection = { ContactsContract.PhoneLookup._ID, ContactsContract.PhoneLookup.NUMBER, ContactsContract.PhoneLookup.DISPLAY_NAME };
Cursor cur = this.getContentResolver().query(lookupUri, mPhoneNumberProjection, null, null, null);
try {
if (cur.moveToFirst()) {
return true;
}
} finally {
if (cur != null)
cur.close();
}
return false;
} else {
return false;
}
}
}
return false;
}// contactExists我的清单中有联系权限
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>我正在搜索，但是我不能理解这个错误。
这是我在Google Play中的轨迹

requestPermissions()是异步的。当它返回时，用户甚至没有被询问权限，更不用说授予你的应用程序任何权限了。
您需要安排在两个点执行联系人查找：
- 如果您在调用
contactExists()(checkSelfPermission()返回PERMISSION_GRANTED)时已经拥有权限，则可以继续执行查找 - 如果您没有权限，则需要等到调用
onRequestPermissionsResult()并确认您现在拥有权限
