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" />

异常

当前回答

只是一个简单的联机程序,不需要任何额外的权限:

private void dialContactPhone(final String phoneNumber) {
    startActivity(new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", phoneNumber, null)));
}

其他回答

一切都很好。

我只是在清单文件中的应用程序标记之前放置了调用权限标记

现在一切都很正常。

 if(ContextCompat.checkSelfPermission(
        mContext,android.Manifest.permission.CALL_PHONE) != 
              PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions((Activity) mContext, new 
                  String[]{android.Manifest.permission.CALL_PHONE}, 0);
                } else {
                    startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Number")));
                }

为了避免这种情况,可以使用GUI来输入权限。Eclipse会考虑在哪里插入权限标记,通常情况下不这样做是正确的

你可以使用Intent。ACTION_DIAL代替Intent.ACTION_CALL。这将显示已输入号码的拨号器,但允许用户决定是否实际拨打电话。ACTION_DIAL不需要CALL_PHONE权限。

清单中的请求权限

<uses-permission android:name="android.permission.CALL_PHONE" />

调用使用此代码

Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:99xxxxxxxx"));
try {
    startActivity(in);
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(mcontext, "Could not find an activity to place the call.", Toast.LENGTH_SHORT).show();
}
