我正在使用以下代码在Android中拨打电话,但它给了我安全例外,请帮助。
posted_by = "111-333-222-4";
String uri = "tel:" + posted_by.trim() ;
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(uri));
startActivity(intent);
权限
<uses-permission android:name="android.permission.CALL_PHONE" />

这个演示对你有帮助…
在呼叫按钮上单击:
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Phone_number"));
startActivity(intent);
舱单许可:
<uses-permission android:name="android.permission.CALL_PHONE" />

你应该把它写在你的清单文件,但同时你应该在运行时问。像这样的代码:
if (ContextCompat.checkSelfPermission(this,android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, arrayOf(android.Manifest.permission.CALL_PHONE),
REQUEST_CODE)
} else {
// else block means user has already accepted.And make your phone call here.
}
如果你想,你可以覆盖onRequestPermissionsResult给用户更好的体验,如果你写相同的代码与else块在这里,你的用户将不需要再次点击你的按钮,在你给予权限后,它将直接调用。
重要提示:
如果你使用Intent。ACTION_CALL必须增加CALL_PHONE权限。
如果你不想让你的应用在没有SIM卡或没有GSM的平板电脑上显示谷歌播放,这是可以的。
在活动中:
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + Constants.CALL_CENTER_NUMBER));
startActivity(callIntent);
清单:
<uses-permission android:name="android.permission.CALL_PHONE" />
因此,如果它不是应用程序的关键功能,尽量避免添加CALL_PHONE权限。
其他解决方案:
是在屏幕上显示手机应用程序,用户只需要点击呼叫按钮:
Intent dialIntent = new Intent(Intent.ACTION_DIAL);
dialIntent.setData(Uri.parse("tel:" + Constants.CALL_CENTER_NUMBER));
startActivity(dialIntent);
这样做不需要许可。
AndroidManifest.xml中的权限
<uses-permission android:name="android.permission.CALL_PHONE" />
完整的代码:
private void onCallBtnClick(){
if (Build.VERSION.SDK_INT < 23) {
phoneCall();
}else {
if (ActivityCompat.checkSelfPermission(mActivity,
Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
phoneCall();
}else {
final String[] PERMISSIONS_STORAGE = {Manifest.permission.CALL_PHONE};
//Asking request Permissions
ActivityCompat.requestPermissions(mActivity, PERMISSIONS_STORAGE, 9);
}
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
boolean permissionGranted = false;
switch(requestCode){
case 9:
permissionGranted = grantResults[0]== PackageManager.PERMISSION_GRANTED;
break;
}
if(permissionGranted){
phoneCall();
}else {
Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}
}
private void phoneCall(){
if (ActivityCompat.checkSelfPermission(mActivity,
Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:12345678900"));
mActivity.startActivity(callIntent);
}else{
Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}
}
