是否因为权限？
我在运行时授予READ_SMS , RECEIVE_SMS, READ_PHONE_STATE权限但仍然崩溃。

还有什么需要做的？
更新
在 Openning_Screen.java 中private void attemptsRegistration() {
Intent intent = new Intent(Opening_Screen.this,PhoneVerification.class);
intent.putExtra(Constant.REQUEST_CODE,55);
startActivityForResult(intent,55);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
final View view = findViewById(android.R.id.content);
if (requestCode == 55){
String result = data.getStringExtra("result");
if (result.equals("PhoneVerifiedSuccessfully")){
RegistrationDataPass.setPhone(data.getStringExtra("phone"));
Intent i = new Intent(Opening_Screen.this,RegPage1.class);
i.putExtra("PhoneNumber",data.getStringExtra("phone"));
startActivity(i);
}else if (result.equals("InvalidCode")){
Constant.showSnak(view,"Registration Failed\nInvalid Code");
}else if (result.equals("INVALID REQUEST")){
Constant.showSnak(view,"Registration Failed\nINVALID REQUEST");
}else if (result.equals("Too many Request")){
Constant.showSnak(view,"Registration Failed\nToo many Requests");
}
}
}
Phone_Verification.java代码非常庞大，我解释它是如何工作的。
当它开始我检查 marshmallow 的权限时，在授予所有权限后，电话号码将被视为来自用户的输入，然后转到verifyPhone()
public void verifyPhone(String phn, PhoneAuthProvider.OnVerificationStateChangedCallbacks _mCallbacks){
mCallbacksResend = _mCallbacks;
Constant.showProgressBar(this,"You will receive an OTP in "+phn);
Log.e("STEP Inside ver pn",phn);
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phn, // Phone number to verify
60, // Timeout duration
TimeUnit.SECONDS, // Unit of timeout
this, // Activity (for callback binding)
_mCallbacks); // OnVerificationStateChangedCallback
}
验证回电就像这样
final PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallBacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
@Override
public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
//progressDialog.dismiss();
Log.d("JEJE", "onVerificationCompleted:" + phoneAuthCredential);
Log.e("STEP in signin","InsideVerification");
signInWithPhoneAuthCredential(phoneAuthCredential);
}
@Override
public void onVerificationFailed(FirebaseException e) {
Constant.hideProgressBar();
Log.w("JEJE", "onVerificationFailed", e);
if (e instanceof FirebaseAuthInvalidCredentialsException) {
Log.d("JEJE", "INVALID REQUEST");
Intent intent = new Intent();
intent.putExtra("result","INVALID REQUEST");
intent.putExtra("phone",phoneNumber);
setResult(REQ_CODE,intent);
} else if (e instanceof FirebaseTooManyRequestsException) {
Log.d("JEJE", "Too many Request");
Intent intent = new Intent();
intent.putExtra("result","Too many Request");
intent.putExtra("phone",phoneNumber);
setResult(REQ_CODE,intent);
}
showSnakBar(e.toString());
//hideProgressDialog();
Constant.hideProgressBar();
Toast.makeText(PhoneVerification.this, "Failed", Toast.LENGTH_SHORT).show();
finish();
}
@Override
public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
super.onCodeSent(s, forceResendingToken);
//hideProgressDialog();
Constant.hideProgressBar();
Log.d("JEJE", "onCodeSent:" + s);
mResendToken = forceResendingToken;
tv.setText("We have sent a verification Code to your number "+phoneNumber+" via SMS.\nEnter the CODE bellow");
phoneNumLayout.setVisibility(View.GONE);
otpLayout.setVisibility(View.VISIBLE);
verifyToken = s;
showTimer();
}
};
在verifyPhone()中显示进度条后，应用程序崩溃了。没有代码被发送。

嗯，问题已经解决了。
我对这个问题的理解是错误的。问题不在于Android版本。每个版本都会出现问题。
<强>原因
正如我所描述的那样，应用程序在调试模式下工作正常，但在发布模式下无效。我用过firebase手机验证。并且需要SHA certificate fingerprints。不幸的是，我忘了提供发布SHA-1。我在发布版本中使用了调试SHA-1指纹。
<强>解决方案
提供发布SHA-1指纹。

IMO您必须将key,value对传递给intent.puExtra()尝试以下代码
intent.putExtra("result",55);
然后您的data.getStringExtra("result");获取值
if (requestCode == 55){
String result = data.getStringExtra("result");
或尝试以下代码可能会有所帮助
Intent intent = new Intent(Opening_Screen.this,PhoneVerification.class);
intent.putExtra(Constant.REQUEST_CODE,55);
intent.putExtra("result",YOUR_RESULT_STRING);
intent.putExtra("phone",PHONE_STRING);
startActivityForResult(intent,55);

在添加@Omi的答案之后，这是另一个你需要提出的条件。
if (requestCode == 55 && data!=null){
//here your code
}
希望得到这个帮助。

转到设置 - ＆gt;开发者选项 - ＆gt;申请部分＆amp; 确保您的“不要保持活动”＃39;选项已关闭然后尝试
