如何解决这个错误：
撤销权限android.permission.CALL_PHONE
这是我的Java代码：
public class DetailContactActivity extends AppCompatActivity implements
OnClickListener {
private TextView phone, email;
private int id;
private ImageView call, btnEmail;
private ContactDB db;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail_contact);
db = ContactDB.getInstance(this);
phone = (TextView) findViewById(R.id.txt_phone_number);
email = (TextView) findViewById(R.id.txt_email);
call = (ImageView) findViewById(R.id.btn_call);
btnEmail = (ImageView) findViewById(R.id.btn_email);
Bundle b = getIntent().getExtras();
if (b != null)
{
id = b.getInt("id");
phone.setText(b.getString("phone"));
getSupportActionBar().setTitle(b.getString("nama"));
if (!b.getString("email").equals("null"))
{
email.setText(b.getString("email"));
} else
{
email.setText("");
}
}
call.setOnClickListener(this);
btnEmail.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.detail_contact, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.action_edit:
Bundle b = new Bundle();
b.putInt("id", id);
b.putString("name", getSupportActionBar().getTitle().toString());
b.putString("email", email.getText().toString());
b.putString("phone", phone.getText().toString());
Intent i = new Intent(this, EditActivity.class);
i.putExtras(b);
startActivity(i);
finish();
return true;
case R.id.action_delete:
showSettingsAlert();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public void onClick(View v)
{
if (v == btnEmail)
{
if (!email.getText().toString().equals(""))
{
Intent emailIntent = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts("mailto", email.getText().toString(),
null));
startActivity(Intent
.createChooser(emailIntent, "Send email..."));
}
} else if (v == call)
{
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + phone.getText().toString()));
startActivity(callIntent);
//Uri call = Uri.parse("tel:" + phone.getText().toString());
//Intent surf = new Intent(Intent.ACTION_CALL, call);
//startActivity(surf);
}
}
private void showSettingsAlert()
{
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Delete");
alert.setMessage("Contact akan dihapus");
alert.setPositiveButton("Ya", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which)
{
db.deleteContact(id);
startActivity(new Intent(DetailContactActivity.this,
MainActivity.class));
finish();
}
});
alert.setNegativeButton("Tidak", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.cancel();
}
});
alert.show();
}
@Override
public void onBackPressed()
{
super.onBackPressed();
startActivity(new Intent(DetailContactActivity.this, MainActivity.class));
finish();
}

切换到DIAL_PHONE，因为它不需要许可。
只需更换此行即可
Intent callIntent = new Intent（Intent.ACTION_CALL）;
至
Intent callIntent = new Intent（Intent.ACTION_DIAL）;
Android 6（SDK 23）允许用户撤消应用程序的权限。我想，那就是这里发生的事情。您的应用必须能够应对这种情况。
详细了解documentation。
特别是：
如果设备运行的是Android 6.0或更高版本，并且您的应用的目标SDK为23或更高：应用必须列出清单中的权限，并且必须在应用运行时请求它所需的每个危险权限。用户可以授予或拒绝每个权限，即使用户拒绝权限请求，应用程序也可以继续以有限的功能运行。
在运行时请求权限是qazxsw poi。
在清单文件中添加此权限：
described in detail here
或者试试这个。
<uses-permission android:name="android.permission.CALL_PHONE"/>
CALL_PRIVILEGED允许应用程序拨打任何电话号码，包括紧急号码，而无需通过拨号器用户界面，以便用户确认正在拨打电话。不适用于第三方应用程序。
我迟到了。您必须动态请求权限。
<uses-permission android:name="android.permission.CALL_PRIVILEGED"/>
更多细节在 // Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Manifest.permission.READ_CONTACTS)) {
// Show an expanation 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(thisActivity,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
请更改call_phone以拨打电话。因为你需要拨号码。
