ApplicationExitInfo


class ApplicationExitInfo : Parcelable
kotlin.Any
   ↳ android.app.ApplicationExitInfo

Describes the information of an application process's death.

Application process could die for many reasons, for example REASON_LOW_MEMORY when it was killed by the system because it was running low on memory. Reason of the death can be retrieved via getReason. Besides the reason, there are a few other auxiliary APIs like getStatus and getImportance to help the caller with additional diagnostic information.

Summary

Public methods
Int

Boolean
equals(other: Any?)

Indicates whether some other object is "equal to" this one.

Int

Return the defining kernel user identifier, maybe different from getRealUid and getPackageUid, if an external service has the android:useAppZygote set to true and was bound with the flag android.content.Context#BIND_EXTERNAL_SERVICE - in this case, this field here will be the kernel user identifier of the external service provider.

String?

The human readable description of the process's death, given by the system; could be null.

Int

The importance of the process that it used to have before the death.

Int

Similar to getRealUid, it's the kernel user identifier that is assigned at the package installation time.

Int

The process id of the process that died.

String

The actual process name it was running with.

ByteArray?

Return the state data set by calling ActivityManager.setProcessStateSummary(byte[]) from the process before its death.

Public methods

describeContents

Added in API level 30
fun describeContents(): Int
Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 30
fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj the reference object with which to compare.
other Any?: This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

getDefiningUid

Added in API level 30
fun getDefiningUid(): Int

Return the defining kernel user identifier, maybe different from getRealUid and getPackageUid, if an external service has the android:useAppZygote set to true and was bound with the flag android.content.Context#BIND_EXTERNAL_SERVICE - in this case, this field here will be the kernel user identifier of the external service provider.

getDescription

Added in API level 30
fun getDescription(): String?

The human readable description of the process's death, given by the system; could be null.

Note: only intended to be human-readable and the system provides no guarantees that the format is stable across devices or Android releases.

getPackageUid

Added in API level 30
fun getPackageUid(): Int

Similar to getRealUid, it's the kernel user identifier that is assigned at the package installation time.

getPid

Added in API level 30
fun getPid(): Int

The process id of the process that died.

getProcessName

Added in API level 30
fun getProcessName(): String

The actual process name it was running with.

Return
String This value cannot be null.

getProcessStateSummary

Added in API level 30
fun getProcessStateSummary(): ByteArray?

Return the state data set by calling ActivityManager.setProcessStateSummary(byte[]) from the process before its death.

Return
ByteArray? The process-customized data This value may be null.

getPss

Added in API level 30
fun getPss(): Long

Last proportional set size of the memory that the process had used in kB.

Note: This is the value from last sampling on the process, it's NOT the exact memory information prior to its death; and it'll be zero if the process died before system had a chance to take the sample.

getRealUid

Added in API level 30
fun getRealUid(): Int

The kernel user identifier of the process, most of the time the system uses this to do access control checks. It's typically the uid of the package where the component is running from, except the case of isolated process, where this field identifies the kernel user identifier that this process is actually running with, while the getPackageUid identifies the kernel user identifier that is assigned at the package installation time.

getRss

Added in API level 30
fun getRss(): Long

Last resident set size of the memory that the process had used in kB.

Note: This is the value from last sampling on the process, it's NOT the exact memory information prior to its death; and it'll be zero if the process died before system had a chance to take the sample.

getStatus

Added in API level 30
fun getStatus(): Int

The exit status argument of exit() if the application calls it, or the signal number if the application is signaled.

getTimestamp

Added in API level 30
fun getTimestamp(): Long

The timestamp of the process's death, in milliseconds since the epoch, as returned by System.currentTimeMillis().
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

Return
Long Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

getTraceInputStream

Added in API level 30
fun getTraceInputStream(): InputStream?

Return the InputStream to the traces that was taken by the system prior to the death of the process; typically it'll be available when the reason is REASON_ANR, though if the process gets an ANR but recovers, and dies for another reason later, this trace will be included in the record of ApplicationExitInfo still. Beginning with API 31, tombstone traces will be returned for REASON_CRASH_NATIVE, with an InputStream containing a protobuf with this schema. Note that because these traces are kept in a separate global circular buffer, crashes may be overwritten by newer crashes (including from other applications), so this may still return null.

Return
InputStream? The input stream to the traces that was taken by the system prior to the death of the process.

getUserHandle

Added in API level 30
fun getUserHandle(): UserHandle

Return the user id of the record on a multi-user system.
